Do digital receivers get discussed here much? I am working on a
receiver for the WWVB signal at 60 kHz and am looking at a very low
power all digital design in an FPGA. Of course some aspects are still
analog such as the antenna. I have been reading about loop antennas for
low frequency work. I don't plan on having an analog amplifier unless
it is needed. I may be able to sample the RF signal directly and use
processing to boost the signal out of the noise.

Has anyone done anything like this? Right now I am looking at how to
synchronize the sample rate with the carrier so that I can accumulate
the signal in a coherent manner.

Any pointers on where I could find more info?
