I hope everyone is well. This one is long and possibly boring. Since now we are apparently all epidimologists I thought I'd give it a try along with everyone else. And I have three technical questions in the below. USA total, and USA by state statistics are available at the COVID Tracking Project among other places. I've seen a lot of actors draw conclusions from such data using pure...

I've been pleased with ease of use of the scipy.signal package for implementing bandpass filters: the `signal.butterworth()`, `signal.sosfilt_zi()` and `signal.sosfilt()` functions do just what I expect for a filter with constant center frequency and bandwidth. But now I'd like to make the frequency and bandwidth settings be time varying functions themselves, and I'm not sure how to

I have followed rick lyons article on this ,and using the example values he gives, the output matches. But using different parameters the filter kenel ends up strangely wiggly. I must be doing something wrong. Here is what i've tried: in maxima: > N:32; > gamma:48/20; > M:N+1; > alpha:cosh(acosh(10^gamma)/N); > A(m):=abs(alpha*cos(%pi

This is probably a stupid question but, well, I'm not all that smart... Instead of going through all the trouble of designing complicated digital filters, why don't we just pick the frequencies that we want to supress and replace those bins in the FFT with zeros?
