step

System object: comm.PAMDemodulator
Package: comm

Demodulate using M-ary PAM method

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) demodulates data, X, with the M-PAM demodulator System object, H, and returns Y. Input X must be a scalar or column vector. The data type of the input can be double or single precision, signed integer, or signed fixed point (fi objects). Depending on the BitOutput property value, output Y can be integer or bit valued.

    Note:   H 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, 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.
