OSM & OAM

OSM & OAM methods are efficient ways to evaluate discrete convolution of a very long signal & a finite impulse response of a digital filter. In OAM, Linear convolution of individual L point sequences is calculated whereas in OSM, Circular Convolution is calculated to obtain the output.In OSM, output is directly obtained by discarding few coefficients from individual stages rather than adding coefficients from OAM method.

  1. FFT algorithm is used in practical systems. But for long input signals(1024 samples) OAM and OSM methods should be used.

  2. why is it referred as block transfer technique?

    1. These are not block transfer techniques but Block processing techniques.

    2. And are used as block processing techniques because input signals are very long length signals.

  3. OSM is preferred for real-time signals
