System object: comm.DifferentialEncoder
Encode binary signal using differential coding
Y = step(H,X)
Y = step(H,X) encodes the binary input data, X, and returns the differentially encoded data, Y. The input X must be a column vector of data type logical, numeric, or fixed-point (embedded.fi objects). Y has the same data type as X. The object treats non-binary inputs as binary signals. The object computes the initial output value by performing an Xor operation of the value in the InitialCondition property and the first element of the vector you input the first time you call the step method.
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.
