Orthogonal Frequency Division Multiplexing, OFDM uses a large number of narrow sub-carriers for multi-carrier transmission to overcome the effect of multi path fading problem. LTE uses OFDM for the downlink, from base station to terminal to transmit the data over many narrow band careers of 180 KHz each instead of spreading one signal over the complete 5MHz career bandwidth. OFDM meets the LTE requirement for spectrum flexibility and enables cost-efficient solutions for very wide carriers with high peak rates.
The primary advantage of OFDM over single-carrier schemes is its ability to cope with severe channel conditions. Channel equalization is simplified. The low symbol rate makes the use of a guard interval between symbols affordable, making it possible to eliminate inter symbol interference (ISI).

REAL TIME SPECIAL EFFECTS GENERATION AND NOISE FILTRATION OF AUDIO SIGNAL USI...ijcsa
Digital signal processing is being increasingly used for audio processing applications. Digital audio effects
refer to all those algorithms that are used for enhancing sound in any of the steps of a processing chain of
music production. Real time audio effects generation is a highly challenging task in the field of signal
processing. Now a day, almost every high end multimedia audio device does digital signal processing in
one form or another. For years musicians have used different techniques to give their music a unique
sound. Earlier, these techniques were implemented after a lot of work and experimentation. However, now
with the emergence of digital signal processing this task is simplified to a great extent. In this article, the
generations of special effects like echo, flanging, reverberation, stereo, karaoke, noise filtering etc are
successfully implemented using MATLAB and an attractive GUI has been designed for the same.

Architecture of direct_digital_synthesizanjunarayanan
A frequency synthesizer is an electronic device which generates a range of frequency mostly sine wave from a fixed clock provided. These frequency synthesizers are commonly found in radio receivers, mobile telephones radio telephones, wacky talkies, as local oscillators, satellite receivers, GPS system. Direct digital synthesizer is a frequency synthesizer which digitally creates arbitrary wave forms of different frequencies from the fixed frequency provided as clock input.DDS generates digital wave forms and these digital waveforms are converted to analog signals by the digital to analog converter connected at the output of DDS. The DDS designed here is a ROM based DDS. DDS has many advantages over PLL and other similar approaches such as fast settling time, sub-Hertz frequency resolution, continuous phase switching response and low phase noise. This system has many applications such as the confidential message transfer, speedy frequency switching.

In today's world we know the importance of encryption and privacy and with data being the most prized possession it is more important than ever to protect that data. Therefore for our project we are aiming at using this as our principal objective for protecting signal and audio during transmission.
To do this will use digital watermarking and using a digital image/unique code superimposing the signal and then transposing that image as a watermark on the audio signal.
Watermarking is a technique used to label digital media by hiding copyright or other information into the underlying data. The aim is to create a watermark that must be imperceptible or undetectable by the user and should be robust to attacks and other types of distortion. In our method, the watermark is kept as a digital image or if contingency arises a masked signal copy.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

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.

10. Sampling
Conversion of a continuous-time signal into a discrete time signal
obtained by taking “samples” of the continuous-time signal as
discrete-time instants
T → sampling interval
Fs(1/T) → sampling frequency (sample/sec, Hz)
12. CONCLUSION
The DSP technology has evolved so much, right from the mid-70's, where it had just one significant
customer in military to the present day DSPs which find application in almost everywhere. The main areas
of this technology would be the cell phones which play a key role in today's voice communication. Digital
Signal Processing (DSP) is often used in modern audio logical equipment. Storage capability
