Convolution

Define convolution among two discret signals in time?
 

Re: Convolution

For example we have two discret signals like x[n] and h[n], convolution among those two signals is signal y[n] and formula is:

y[n]=x[n]*h[n]={x[k]h[n-k]

where * is a symbol of convolution { iz a SUM that goes from k=-infinity to k=+infinity.

This is applied very much in DSP and similary themes...

Re: Convolution

hi

x[n]*h[n]=Σx[k].x[n-k]
for k=-inf to inf

bye
 

Re: Convolution

convolution in time domain yields to multipulation in frequency domain and oposite
