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.synthesizeDSM() 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
