Unit Delay

Delays the input signal by a sample period

Description

The Unit Delay component is described as follows:

y=uz

The output signal, y, is the input signal, u, of the previous sample instant. Before the second sample instant, the output, y, is identical to the parameter, y0.

The Signal Size parameter allows the block to operate on a vector of signals rather than a single signal.
