... applies to low- delay FIR
filter designs [9].
In the past, many attempts to design FIR lowpass filters
with low group delay have been made [9–12]. In [13], a
procedure for the design of FIR Nyquist ... the mean
value of the group delay is restricted to integer multiples of
the number of channels.
For the first design step we have introduced a novel
procedure for the design of low- delay AFB FIR ... resulting
in an oversampling factor of O
= 4.
5.1. AFB Prototype Filter. First we start with the design of
a narrow-band FIR low- pass AFB prototype filter with low
group delay designed by using the algorithm...
