Digital filter Frequecy response plotter
This page plots frequency and phase response for FIR and IIR digital filters.
IIR - Second order sections
IIR - numerator, denominator
Filter coefficients (convolution kernel), separated by commas. Fixed or floating point. (Can include or ommit brackets etc)
Array of second-order filter coefficients, must have shape (n_sections, 6). Fixed or floating point. Each row corresponds to a second-order section, with the first three columns providing the numerator coefficients and the last three providing the denominator coefficients.
Numerator (b) polynomial coefficients, separated by commas. Fixed or floating point. (Can include or ommit brackets etc)
Denominator (a) polynomial coefficients, separated by a comma (Can include or ommit brackets etc)
Sample rate, in Hz
