System object: comm.FMModulator
Package: comm
Applies FM baseband modulation
Y = step(H,X)
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) frequency modulates an input
signal, X, and returns a modulated signal, Y.
The input X is real or complex and can be either
a scalar or a column vector. Double- and single-precision data types
are supported. The output Y has the same data
type and dimensions as X.
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 (MATLAB) and input specifications, such as dimensions,
complexity, and data type of the input data. If you change a nontunable
property or an input specification, the System
object issues an
error. To change nontunable properties or inputs, you must first call
the release method to unlock the object.
