CONVOLUTION
a=input('enter the first sequence=')
b=input('enter the second sequence=')
f=conv(a,b)
subplot(2,2,1)
stem(a)
xlabel('time index')
ylabel('amplitude')
subplot(2,2,2)
stem(b)
xlabel('time index')
ylabel('amplitude')
subplot(2,1,2)
stem(f)
xlabel('time index')
ylabel('amplitude')
title('linear convolution of two sequence')
Observation:
enter the first sequence=[1,2,3,4]
a = 1 2 3 4
enter the second sequence=[1,4,3,5]
b = 1 4 3 5
f = 1 6 14 27 35 27 20
