step

System object: comm.FSKModulator
Package: comm

Modulate using M-ary FSK method

Syntax

Y = step(H,X)

Description

Y = step(H,X) modulates input data, X, with the FSK modulator System object™, H. It returns the baseband modulated output, Y. Depending on the value of the BitInput property, input X can be an integer or bit- valued column vector with numeric or logical data types. The length of output vector, Y, is equal to the number of input samples times the number of samples per symbol you specify in the SamplesPerSymbol property.

    Note:   The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties 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.
