step
System object: comm.DiscreteTimeVCO
Namespace: comm
Generate variable frequency sinusoid
Syntax
Y = step(H,X)
Description
Note
Starting in R2016b, instead of using the step
method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x)
and y = obj(x)
perform equivalent operations.
Y = step(H,X)
generates a sinusoidal signal, Y
,
with frequency shifted, from the value you specify in the QuiescentFrequency
property,
to a value proportional to the input signal, X
.
The input, X
, must be a double or single precision,
real, scalar value. The output, Y
, has the same
data type and size as the input, X
.
Note
obj
specifies the System object on which to run this step
method.
The object performs an initialization the first time the step
method is executed. This initialization locks nontunable properties and
input specifications. For more information on changing property values, see System Design in MATLAB Using System Objects.
