I am tryng to implement the following example. And i get an error. What could be the reason?
code:
audio = dsp.AudioFileReader('guitartune.wav','SamplesPerFrame',4410);
fmbMod = comm.FMBroadcastModulator('AudioSampleRate',audio.SampleRate, ...
'SampleRate',240e3);
fmbDemod = comm.FMBroadcastDemodulator( ...
'AudioSampleRate',audio.SampleRate, ...
'SampleRate',240e3,'PlaySound',true);

Those are Communications Toolbox functions. You should be able to use them if you have the Communications Toolbox installed.

Note that R2019a will be out in the not distant future. It promises a number of bug fixes, as well as new functionality.
