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: order : int
the transfer function order
alpha : float
parameter controlling the steepness of the magnitude response
Returns: zeros : ndarray
an array of complex roots of the FIR transfer function
