Computation of the impulse response of a DT filter (pydsm.ir)¶
Compute (approximating by truncation) the impulse response of a discrete time filter, trying to (roughly) guess the appropriate truncation.
Functions¶
guess_ir_length(h[, db]) | Tries to estimate an appropriate length for the filter response |
impulse_response(h[, m, db]) | Computes the filter impulse response |
