MATLAB: Does the “freqdev” parameter for the FMMOD function in the Communications Toolbox documentation define the maximum frequency deviation from the carrier or the frequency deviation constant

Question

I am not sure whether the "freqdev" parameter for the FMMOD function in the Communications Toolbox documentation defines the maximum frequency deviation from the carrier or the frequency deviation constant.

Answer 1

This change has been incorporated into the documentation in Release 14 Service Pack 3 (R14SP3). For previous releases, read below for any additional information:

We have verified that documentation on the FMMOD function is not clear in the Communications Toolbox manual.

Here is some additional information on the FMMOD function:

The "freqdev" parameter refers to the frequency deviation constant and NOT the maximum frequency deviation from the carrier frequency.
