firlp2lp
Transform FIR Type I lowpass to FIR Type 1 lowpass with inverse bandwidth
Syntax
Description
transforms the Type I lowpass FIR filter g
= firlp2lp(b
)b
with zero-phase
response Hr(w) to a Type I lowpass FIR filter g
with zero-phase
response [1 - Hr(π-w)].
When b
is a narrowband filter, g
will be a
wideband filter and vice versa. The passband and stopband ripples of
g
will be equal to the stopband and passband ripples of
b
, respectively.
