pydsm.NTFdesign.helpers.maxflat_fir_zeros

pydsm.NTFdesign.helpers.maxflat_fir_zeros(order, alpha)

Compute the zeros of a maxflat FIR transfer function.

The computed FIR transfer function is used in the DELSIG pydsm.delsig.synthesizeNTF() design method (also known as pydsm.NTFdesign.ntf_schreier()) for the denominator of the noise transfer function.

Parameters:

orderint

the transfer function order

alphafloat

parameter controlling the steepness of the magnitude response

Returns:

zerosndarray

an array of complex roots of the FIR transfer function
