Hi John,Indeed, to understand the plots you need to study "a little" at least digital signal processing... If you encounter some difficulties with Rick's book (I...

Re: Understanding the Comb Filter Frequency Response

Hi,I can propose another way to understand how to build the spectrum of a comb filter, either recursive or not, and also its impulse response.1. Study of unit...

Re: The Spectral Complexity of a Single Musical Note

Reply posted 1 year ago (02/19/2019)
Hi,I suspect also that the data acquisition system includes a high-pass filter with a cutoff frequency around 100 Hz, in order to suppress at least the contribution...
Hello John,Your filter is a linear phase FIR lowpass filter:- FIR: finite impulse response;- linear phase: the phase plot gives a line for most of the frequencies...
