frest.createFixedTsSinestream

Package: frest

Sinestream input signal with fixed sample time

Syntax

input = frest.createFixedTsSinestream(ts)

input = frest.createFixedTsSinestream(ts,{wmin wmax})

input = frest.createFixedTsSinestream(ts,w)

input = frest.createFixedTsSinestream(ts,sys)

input = frest.createFixedTsSinestream(ts,sys,{wmin wmax})

input = frest.createFixedTsSinestream(ts,sys,w)

Description

input = frest.createFixedTsSinestream(ts) creates sinestream input signal in

which each frequency has the same fixed sample time ts in seconds. The signal has 30

frequencies between 1 and ωs, where ωs=

2 π

ts

is the sample rate in radians per second.

The software adjusts the SamplesPerPeriod option to ensure that each frequency has

the same sample time. Use when your Simulink model has linearization input I/Os on

signals with discrete sample times.

input = frest.createFixedTsSinestream(ts,{wmin wmax}) creates sinestream

input signal with up to 30 frequencies logarithmically spaced between wmin and wmax in

radians per second.

input = frest.createFixedTsSinestream(ts,w) creates sinestream input signal

with frequencies w, specified as a vector of frequency values in radians per second. The

values of w must satisfy w=

2 π

Nts for integer N such that the sample rate ωs=

2 π

ts is an

integer multiple of each element of w.
