The following figure shows the prototypical discrete-time signal discussed in Discrete-Time Signals. If this signal were propagated through a model sample-by-sample, rather than in batches of samples, it would be called sample-based. It would also be called single-channel, because there is only one independent sequence of numbers.
In practice, signal samples are frequently transmitted in batches, or frames, and several channels of data are often transmitted simultaneously. Hence, the general signal is frame-based and multichannel.
The following sections explain how sample-based and frame-based multichannel signals are represented in Simulink:
The representation of single-channel signals follows naturally as a special case (one channel) of the general multichannel signal.
