Hi everybody! I need to recover the signal captured by 3 or 4 hydrophones and doing the respective signal processing (amplification, filtering, ADC). What kind of microcontroller should I use in order to do that? The recovered signal should be between 25 kHz and 200 kHz.
Thanks!
 
I don't think an MCU can handle filtering for that many signal sources at those frequencies on top of everything else at those bandwidths. Could be wrong though.
 
One example is to record all 4 signals for 10,000 samples then go back and process them in NOT-real time.
There are DSPs that probably can do that in real time. Could use 4 small DSP parts.
A DSP is made to do this job, but is not a good microcontroller for general purpose applications.

The dsPIC's are pretty good general purpose micro-controllers (it's just the usual PIC core), I've no idea how they are as DSP's though? - I keep meaning to have a play with one.
