I need help deciding on whether to use a digital or analog filtering design. I have a 100 uV signal that I need to amplify 10,000x and bandpass filter for 500-5,000 Hz. I want to sample this signal with a SoC or microcontroller at a rate of at least 10 kHz and send the data to a PC. Power and size are of major concern in this design.
My thoughts are as follows, but may be incorrect:
If I use a digital filter, I could implement the bandpass filtering on the PC to conserve space and power. I would still need to amplify and perform anti-aliasing filtering on the circuit. Would this really conserve any space?
Any thoughts from the more experiences people here?
