Savitzky-Golay convolution filter

CasLotter1

What will a 249 coefficient savitzki-golay convolution filter looks like? Anybody calculated the coefficients?

This is what AI answers (in which window size will translate to number of coefficients):

A 249-coefficient Savitzky-Golay convolution filter is a zero-phase, symmetric Finite Impulse Response (FIR) filter whose exact shape depends entirely on your chosen polynomial order (assuming a 0th-order derivative for data smoothing). [1, 2]Because the window size is very large (\(N=249\)), the individual coefficient magnitudes are small (peaking under 0.02), and the filter will act as a deep low-pass smoothing mechanism

@VictorSavenije @VictorAwosiji @ManuelaBiondo in case this is in your wheelhouse! Any thoughts that might help @CasLotter1 here? 😊
