In previous experiments, FFT was used on short sequences of input. However, in real time, discretized input sequence is very long. This large sequences can't be processed directly. They are first divided into blocks and then thus the real time signal is processed, using DITFFT, block by block. This block of output sequence is then combined together using OAM or OSM and final output is obtained.

DeleteOSM is mostly used.
ReplyDeleteYes as it is more efficient

ReplyDeleteOAM has lesser computations
ReplyDeleteHowever, OSM is efficient when used in real-time.
