Re: [linrad] DSP Question

Hello, Mark !

You can design an LPF and then multiply it's taps by the
complex sinusoid exp(j*w0*t). This will result in a two sets of
coefficients (real and imaginary). Each set represents a BPF
centered at w0, but the two filters will have 90 degree phase 
response difference.

I use such technique in my HF DSP transceiver design.

All the best !
