Frame-Based Signal Nomenclature

A frame of data is a collection of sequential samples from a single channel. In Simulink, a length-M frame of data is represented by an M-by-1 matrix (column vector). A multichannel signal with N channels and M samples per frame is represented as an M-by-N matrix. See Multichannel Signals for more about multichannel signals.

Signals in Simulink can be either frame-based or sample-based. You can typically specify the frame status (frame-based or sample-based) of any signal that you generate using a source block (from the DSP Sources library). Most other DSP blocks generally preserve the frame status of an input signal, but some do not. See Creating Signals for more information.
