Overlap-Add and Overlap-Save method is used to perform linear convolution and circular convolution of long data sequences respectively. They are called as block processing techniques as the input signal is divided into blocks and then analysed. The OAM was performed by linear convolution using DITFFT and OSM by Circular Convolution using DITFFT. In case of OSM the input signal was modified and the final output signal was obtained by discarding few initial values from all the convolved outputs.

ReplyDeleteShort n crisp!
ReplyDeleteWhich method is better?
ReplyDeleteOsm is better tham oam
ReplyDeleteOSM and OAM can only be used for FIR Filters
ReplyDeleteOsm does not require memory as it discards values
ReplyDeleteThese methods are uesd in FIR filters
ReplyDeletethis is block processing technique
ReplyDeleteOam and osm camnot be used for IIR filter
