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.

This question settles it then. I am buying the latest version one. 2018b....here i come, for YOU!!!

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