System object: comm.BasebandFileWriter
Package: comm

Write baseband signal to file





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.

step(bbw,x) writes a baseband signal, x, to the file specified by the Filename property of the BasebandFileWriter object, bbw. The number of samples written to the file is determined by the NumSamplesToWrite property of bbw.

bbw(x) is equivalent to the first syntax.


bbw 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.
