I am a bit confused with convolution in the context of DSP.
The definition I have for convolution is as follows: if delta of n is applied to a digital system then the output will be the impulse response of the system h[n]. The impulse response can be determined by looking at the original function and replacing x[n] by delta[n]. Once we have the impulse function that is then convolved with x[n]. i.e. y[n]=x[n]*h[n].
My confusion is this is it the same x[n] that is convolved with h[n] that was used to create h[n]. Or was h[n] created using a separate x[n] to the one convolved with h[n].
