Unable to generate chirp signal in wireless waveform generator app

It seems that there is no option to generate linear frequency modulation signals (i.e. chirp signals) in the MATLAB wireless waveform generator app, and other basic signals such as triangular waves do not seem to be available. Can someone tell me how to generate chirp signals in the wireless waveform generator app?

Hi,

The linear FM or chirp signal generation functionality has been introduced in R2022b as per the following release notes:

I recommend updating MATLAB to R2022b or a newer release to avail this functionality.

You can refer to the following documentation to know how to use the “Linear FM” tab in Wireless Waveform Generator App:

Additionally, you can refer to the following documentation to setup triangular modulation for linear FM signals:

I hope this resolves your issue.
