step
System object: comm.DifferentialEncoder
Package: comm
Encode binary signal using differential coding
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)
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
obj
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. For more information on changing property values, see System Design in MATLAB Using System Objects.
