- % MATLAB script for Illustrative Problem 6.10.
- echo on
- T=1;
- Fs=2/T;
- Ts=1/Fs;
- c_opt=[-2.2 4.9 -3 4.9 -2.2];
- t=-5*T:T/2:5*T;
- x=1./(1+((2/T)*t).^2); % sampled pulse
- equalized_x=filter(c_opt,1,[x 0 0]); % since there will be a delay of two samples at the output
- % to take care of the delay
- equalized_x=equalized_x(3:length(equalized_x));
- % Now, let us downsample the equalizer output.
- for i=1:2:length(equalized_x),
- downsampled_equalizer_output((i+1)/2)=equalized_x(i);
- echo off;
- end;
- echo on ;
- % Plotting commands follow.
