Thinks Another: Using Spectrograms to Identify Stage Wiggliness?

March 2, 2021 | Tony Hirst

Last night I started wondering about ways in which I might be able to use signal processing (Fourier analysis) or symbol dynamics (eg Thinks: Symbolic Dynamics for Categorising Rally Stage Wiggliness?) to help categorise the nature of rally stage twistiness. Over a morning coffee break, I reminded myself of spectrograms, ...
