fdesign.polysrc
Construct polynomial sample-rate converter (POLYSRC) filter designer
Syntax
d = fdesign.polysrc(l,m)
d = fdesign.polysrc(l,m,'Fractional Delay','Np',Np)
d = fdesign.polysrc(...,Fs)
Description
d = fdesign.polysrc(l,m)
constructs
a polynomial sample-rate converter filter designer D with an interpolation
factor L and a decimation factor M. L defaults to 3. M defaults to
2. L and M can be arbitrary positive numbers.
d = fdesign.polysrc(l,m,'Fractional Delay','Np',Np)
initializes
the filter designer specification with Np and sets the polynomial
order to the value Np. If omitted Np defaults to 3.
d = fdesign.polysrc(...,Fs)
specifies
the sampling frequency (in Hz).
