qp_kaiser

-

Computes a finite impulse response (FIR) filter for use with a quasi-perfect reconstruction polyphase-network filter bank.

- - -

Calling Sequence

- 
qp_kaiser (nb, at, linear)
-qp_kaiser (nb, at)
- -

Parameters

-
nb: -

Number of bands

-
at: -

Attenuation

-
linear: -

When not zero, minimum-phase calculation is omitted.

- -

Description

-

This is an Octave function. -This version utilizes a Kaiser window to shape the frequency response of the designed filter. Tha number nb of bands and the desired attenuation at in the stop-band are given as parameters.

-

The Kaiser window is multiplied by the ideal impulse response h(n)=a.sinc(a.n) and converted to its minimum-phase version by means of a Hilbert transform.
