/*
Example of use of the FFT libray to compute FFT for several signals over a range of frequencies.
The exponent is calculated once before the excecution since it is a constant.
This saves resources during the excecution of the sketch and reduces the compiled size.
Example of use of the FFT library to compute FFT for several signals over a range of frequencies.
The exponent is calculated once before the execution since it is a constant.
This saves resources during the execution of the sketch and reduces the compiled size.
The sketch shows the time that the computing is taking.
