Y = step(H,X)
Y = step(H,X) modulates input data, X, with the CPFSK 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 data types double, signed integer, or logical. The length of output vector, Y, is equal to the number of input samples times the number of samples per symbol specified 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.
