Member of the waveform generation class.

Syntax

[x, t] = gensig(type, period)

[x, t] = gensig(type, period, duration)

[x, t] = gensig(type, period, duration, interval)

Description

Generates periodic signals.

Examples

Inputs

Name	Description
type	Specifies the type of signal to generate. type is a string that accepts the following values. 'pulse' Generates a periodic pulse. 'sin' Generates a sine wave. 'square' Generates a square wave.
period	Specifies the period of the signal. period is a real scalar.
duration	Specifies the time duration, in seconds, of the signal. duration is a real scalar. The default is 5.
interval	Specifies the time interval, in seconds, between two samples. interval is a real scalar. The default is 0.015625, or 1/64.

Outputs

Name	Description
x	Returns the amplitude of the generated signal. x is a vector.
t	Returns the time values of the generated signal. t is a vector.

Examples

[X, T] = gensig('sin', 100, 100, 1)
plot(T, X)
