Can I use this block on the output of a bandpass filter that doesn't
downconvert to baseband, or must
the data always be basebanded?
I have an application (a VLF receiver application) it uses the audio
subsystem to sample from
around DC to around 40KHz or so, and carves off up to 4 narrowband
(100Hz to 400Hz)
subchannels from those, and needs to demodulate (FSK or MSK) those
subchannels.
Do I need to do anything special after the channel filters?
