AREA
The project is based on Channel Equalization which is veryimportant in digital communication.
Its purpose is to reduce inter-symbol interferences.
Through which we get the original transmitted signals.
There are many types of Equalizers: Zobel Network, LatticePhase Equalizer, Bridged T Delay Equalizer, etc.

PROBLEM
When the signal (e.g. radio, electrical) is transmitted,
it is in its original form without any noise.
Same is not the case when the signal is received.
As it passes through a medium (e.g. air, wire) it addsup unwanted signals which ruin the signal.

RELATED RESEARCH
All the equalization can be done by manipulating with thefrequency of the signals.
As the frequency is manipulated with we can block thefrequency at which we detect the noise and let others pass.
The frequency can be manipulated by passing the signalthrough high pass, low pass , band pass, high shelvingband and low shelving band.

SOLUTION
The solution to removing noise is or altering the signal
to get the original unfiltered signal.
For this we will use a channel equalizer.
In Equalizers, we will specifically be using a ZobelNetwork filter.

ADVANTAGES
Equalization overcomes Inter-Symbol Interferences
(ISI).
They are used in audio devices to control base, treble,etc.

DISAVANTAGES
By removing or altering the frequency on which there
is noise, we might also eliminate or alter the signal onthe same frequency.

NEW IDEA PROPOSED
Verification of the proposed model for channel
equalization for more number of input continuoussignals like speech signals of approximately samefrequency.
