System object: comm.DBPSKModulator
Modulate using DBPSK method
Y = step(H,X)
Y = step(H,X) modulates input data, X, with the DBPSK modulator System object™, H. It returns the baseband modulated output, Y. The input must be a numeric or logical data type column vector of bits.
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.
