trans
low-pass to other filter transform
Calling Sequence
hzt=trans(hz,tr_type,frq) hzt=trans(pd,zd,gd,tr_type,frq)
Arguments
- hz
a single input single output discrete transfer function, the low pass filter
- pd
Vector of given filter poles
- zd
Vector of given filter zeros
- gd
scalar: the given filter gain
- tr_type
string, the type of transformation, see description for possible values
- frq
2-vector of discrete cut-off frequencies (i.e.,
0<frq<.5
). see description for details.- hzt
transformed filter transfert function.
Description
function for transforming standardized low-pass filter given its poles-zeros_gain representation into one of the following filters:
- tr_type='lp'
low pass filter, the cutoff frequency is given by the first entry of
frq
, the second one is ignored.- tr_type='hp'
high pass filter, the cutoff frequency is given by the first entry of
frq
, the second one is ignored.- tr_type='bp'
band pass filter, the frequency range is given by
frq(1)
andfrq(2)
.- tr_type='sb'
stop band filter, the frequency range is given by
frq(1)
andfrq(2)
.
