3 Accuracy of Sampling Let us sample the function gt)cos(2fo) at sampling interval dt- 1, for...

The required MATLAB CODE is as follows:

fs=0.01; %Very high sampling rate
f=1; %Frequency of sinusoid
nCyl=5; %generate five cycles of sinusoid
maxf=nCyl*f;
t=0:fs:maxf; %time index
x=cos(2*pi*f*t); % continious wave

fs1=0.25; %1/0.25 sampling rate
t1=0:fs1:maxf; %time index
x1=cos(2*pi*fs1*t1);

fs2=0.75; % 1/0.75 sampling rate
t2=0:fs2:maxf; %time index
x2=cos(2*pi*fs2*t2);

figure
subplot(2,1,1);
plot(t,x);
hold on;
stem(t1,x1); % plot the first sample
xlabel('Time(s)');
ylabel('Amplitude')
title('f=0.25');

subplot(2,1,2);
plot(t,x);
hold on;
stem(t2,x2); % plot the first sample
xlabel('Time(s)');
ylabel('Amplitude')
title('f=0.75')
