Convolution and Correlation

Length of output Convoluted signal equaled to sum of length of both input signals - 1. Length of Circular convoluted signal is the max of both input signals. Output of Auto correlated signal was same as that without delayed input signal. Length of output Cross correlation signal equaled to sum of length of both input signals - 1. Cross correlation with one input signal gives delayed output.

  1. If both x[n] and h[n] are causal then the resultant y[n] is also causal.

  2. Correlation compares two signals while convolution is used to get output of filter.

  4. Correlation gives degree of similarity between two input signals.It is used in radar systems to locate target.

  5. Correlation gives similarity of signals. It is used in Audio Feature Extraction to compare the extracted signal with the reference signal.
