The concept of Linear Convolution , Circular Convolution and Correlation was taught in Signal and Systems . So from this experiment what we learnt that lenght of linear convoltuion o/p signal is N=L+M-1 where , L is the length of first i/p signal & M is the length of the second i/p signal & N is the linear convolution o/p signal length .
As both the i/p signals are causal, the o/p is also causal.
Length of circular convolution o/p signal N=max(L,M) where L is the length of the first i/p signal and M is the length of the second i/p signal and N is the length of the o/p signal which is also the maximum of L and M .
For linear convolution using Circular convolution :- N>= L+M-1

If both x[n] and h[n] are causal then the resultant y[n] is also causal.
ReplyDeleteAliasing error is an interesting phenomena, mention about it.
ReplyDeleteyes @nikhil nandoskar . Both the i/p signals were causal and so the o/p had to be a causal signal .
ReplyDeleteAliasing error is basically an overlapping error @Ameya Lokre . To remove this error a filter is used .
