The document discusses band pass filters, which are electronic devices that allow signals between two specific frequencies while rejecting others, combining properties of low and high pass filters. It describes two types of band pass filters: active (requiring external power) and passive (using only passive components), along with schematic diagrams for both. Applications include their use in wireless transmitters and receivers, where they limit bandwidth and allow for the decoding of signals within a specific frequency range.

2. OUTLINE:
 BAND PASS FILTER
 SCHEMATIC DIAGRAM
 WAVEFORM
 TYPES OF BAND PASS FILTER :
 APPLICATIONS OF BAND PASS FILTER
 SIMULATION OF BAND PASS FILTER

3.  BAND PASS FILTER:
 A Band pass filter is an electronic device or
circuit that allows signal between two specific
frequencies to pass but that discriminates the
signals at other frequencies .
 Band pass filter is the filter which have
properties of both low pass Filter and high pas filter .

4. SCHEMATIC DIAGRAM:

5. WAVEFORM:

6. So in waveform:
 Fl : low pass filter frequency
 FH : high pass filter frequency
 Fo: geometric center frequency
 B : band width

7. Types of band pass filter:
 There are two types of band pass filter
1. Active band pass filter:
It is a band pass filter
which require an external source of power and employ active
Component such as transistor and integrated circuits are
known as active Band pass filter.

8.  Circuit diagram of Active band pass filter:

9. 2: Passive band pass filter:
The band pass filter
which not use external source of power and
consist only of passive components such as
capacitors inductors these are called passive band
pass filter

10.  Diagram of passive band pass filter:

11.  Applications of band pass filter:
Band pass filter used
in main two things which are given below.
 Wireless transmitter
 Wireless receiver.
And the main function in both types are given below.

12.  Wireless transmitter
The main function of such a filter in a
transmitter is to limit the bandwidth of the output signal to
the band allocated for the transmission. This prevents the
transmitter from interfering with other station

13.  Wireless receiver.
In a receiver, a band pass filter allows
signals within selected range of frequencies to be heard or
decoded, while preventing signals at unwanted frequencies
from getting through other stations.

14.  SIMULATION: 1 TO 100 HZ BAND PASS FILTER;
