We were able to implement this quiet well as compared to last three experiments. In this Implementaion of Long Input Sequence using Overlap Add Method and overlap save method. length of input signal and input signal values as an input are taken from user.Taking length of impulse response and signal values of impulse response as an input from user. Here long input sequence is broken down into small sequences of equal length, then using zero padding and FFT corresponding X[K] is obtained. Then all these X[K] are added to get final output. Overlap add method is used to process real-time signal which have no defined end. overlap save method is used to evaluate discrete convolution between a very long signal X(n) and a finite impulse response h(n).
OAM is slower as compared to OSM and hence should be used often as the number of steps are reduced in this method.
ReplyDeleteRight, but for small length computation OAM can also be used.
