I have what may be an odd question for the SDR gurus out there.
What would be the physical implementation (in software) of a broadband frequency divider?
For example, say I want to capture a signal at, 1 GHz, with a 10 MHz bandwidth, then divide it by a factor of 10,
I should get a down-sampled signal at 10 MHz with a 1 MHz bandwidth.
Yes, I know I would lose information, but assume this would be presented as a spectrum analysis, not full audio, video, etc.
Conceptually, could this be accomplished by sampling the RF at 2+times the highest frequency components, say at 2.5 GHz, then discarding 9 out of 10 samples - decimating the input stream?
Thanks,
Dave
