Discrete Impulse

Generates a discrete pulse.

discrete impulse

Description

Block Discrete Impulse generates a pulse (of value 1) on -th count, where is defined by parameters Delay (samples). All output samples preceding and following -th sample are equal to zero.

When is a vector of length , the block generates a matrix of size by , where is the number of individual channels and is the frame size, which is defined by the parameters . Samples per frame. The pulse of - the second channel appears on countdown.

The value of parameters Sample time, , determines the reference period of the output signal. The resulting frame period is equal to .

Ports

Output

# OUT_1 — discrete pulse signal
scalar | vector | matrix

Details

Output signal containing a discrete pulse at -sample, where is a scalar or vector given by parameters Delay (samples).

Parameters

Main

# Delay (samples) — number of output samples with zero value
Scalar / array of Int64

Details

Number of zero output samples, , preceding the pulse. Set as a scalar or vector of integer values greater than or equal to zero. If the parameters Delay (samples) is set as a vector of length , the output is formed -channel signal.
