Introduction
Band Pass Amplifiers
Series & Parallel Resonant Circuits & their Bandwidth
Analysis of Single Tuned Amplifiers
Analysis of Double Tuned Amplifiers
Primary & Secondary Tuned Amplifiers with BJT & FET
Merits and de-merits of Tuned Amplifiers
The performance obtainable from a single-stage amplifier is often insufficient for many applications, hence several stages may be combined forming a multistage amplifier. These stages are connected in cascade, i.e. output of the first stage is connected to form input of second stage, whose output becomes input of third stage, and so on.

Salient Features:
The magnitude response is nearly constant(equal to 1) at lower frequencies
There are no ripples in passband and stop band
The maximum gain occurs at Ω=0 and it is H(Ω)=1
The magnitude response is monotonically decreasing
As the order of the filter ‘N’ increases, the response of the filter is more close to the ideal response
In signal processing, a digital filter is a system that performs mathematical operations on a sampled, discrete-time signal to reduce or enhance certain aspects of that signal. This is in contrast to the other major type of electronic filter, the analog filter, which is an electronic circuit operating on continuous-time analog signals.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

3. DEFINITION:-
An amplifier circuit in which the load circuit is a
tank circuit such that it can be tuned to pass or amplify
selection of a desired frequency or a narrow band of
frequencies, is known as Tuned Circuit Amplifier.
K V VENKATARAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
4. CHARACTERISTICSOFTUNEDAMPLIFIER
Tuned amplifier selects and amplifies a single frequency
from a mixture of frequencies in any frequency range.
A Tuned amplifier employs a tuned circuit.
It uses the phenomena of resonance, the tank circuit which
is capable of selecting a particular or relative narrow band
of frequencies.
The centre of this frequency band is the resonant frequency
of the tuned circuit .
Both types consist of an inductance L and capacitance C
with two element connected in series and parallel.
K V VENKATARAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
5. RESONANCECIRCUITS:
•When at particular frequency the inductive reactance
became equal to capacitive reactance and the circuit then
behaves as purely resistive circuit. This phenomenon is
called the resonance and the corresponding frequency is
called the resonant frequency.

9. CLASSIFICATIONOFTUNED
AMPLIFIERS
Small Signal Tuned Amplifiers :- They are used to amplify
the RF signals of small magnitude.
They are further classified as:
(a)Single Tuned Amplifiers:- In this we use one
parallel tuned circuit in each stage.
(b)Double Tuned Amplifiers:- In this we use two
mutually coupled tuned circuits for every stage both of
tuned circuits are tuned at same freq.
(c)Stagger Tuned Amplifiers:- It is a multistage amplifier
which has one parallel tuned circuit for every stage but
tuned frequency for all stages
K V VENKATARAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
10. (2) Large signal tuned amplifiers:-
They are meant for amplifying large signals in which
large RF power is involved & distortion level is also
higher. But tuned circuit itself eliminates most of the
harmonic distortion.
K V VENKATARAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
11. SERIESRESONANT CIRCUIT
•It is the circuit in which all the resistive and
reactive components are in series.
K V VENKATARAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
16. QUALITYFACTOR:
• It is voltage magnification that circuit produces at
resonance is called the Q factor.
Imax XL
/ Imin R• Voltage Magnification =
= XL/ R
• At Resonance =
XL/R = XC/R
ωrL / R = 1 /

17. THUS
Qr = ωrL / R = 1/ ωrC R
= 2 π fr L / R
= (2 π L / R) * (1 / 2 π √LC )
= √(L/C) / R
=
{ tan Ф = power factor of coil }
tanФ
K V VENKATARAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
18. IMPORTANTPOINTS
(1) Net reactance , X = 0.
(2) Impedance Z = R .
(3) Power factor is unity.
(4) Power expended = 6 watt.
•
•
Current is so large & will produce large voltage
across inductance & capacitance will be equal in
magnitude but opposite in phase.
Series resonance is called an acceptor circuit
because such a circuit accepts current at one
particular frequency but rejects current at other
frequencies these circuit are used in Radio –
receivers .
K V VENKATARAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
21. PARALLELORCURRENTRESONANCE
•When an inductive reactance and a capacitance are connected in
parallel condition may reach under which current resonance (also
known as parallel or anti- resonance ) will take palace.
•The frequency at which this happened is known as resonant
frequency. Current will be in resonance I reactive component of R -
L branch.
•IR-L sinФ R-L = Reactive component of capacitive branch,
neglecting leakage reactance of capacitor C.
K V VENKATA RAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
32. LIMITATION:
• This tuned amplifier are required to be highly selective.
But high selectivity required a tuned circuit with a high Q-
factor .
• A high Q- factor circuit will give a high Av but at the
same time , it will give much reduced band with because
bandwidth is inversely proportional to the Q- factor .
• It means that tuned amplifier with reduce bandwidth may
not be able to amplify equally the complete band of
signals & result is poor reproduction . This is called
potential instability in tuned amplifier.
K V VENKATA RAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
56. APPLICATIONS OF TUNED AMPLIFIER
Tuned amplifiers serve the best for two purposes:
a) Selection of desired frequency.
b) Amplifying the signal to a desired level.
USED IN:
Communication transmitters and receivers.
In filter design :--Band Pass, low pass, High pass and
band reject filter design.
K V VENKATA RAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
57. ADVANTAGES
It provides high selectivity.
It has small collector voltage.
Power loss is also less.
Signal to noise ratio of O/P is good.
They are well suited for radio transmitters and
receivers .
K V VENKATA RAMANA‖ ECA ‖ Dept of ECE ‖ ISTS
58. DISADVANTAGES
They are not suitable to amplify audio
frequencies.
If the band of frequency is increase then design
becomes complex.
Since they use inductors and capacitors as tuning
elements, the circuit is bulky and costly.
