#128459 - Active filters Responding to: ???'s previous message |
Hi, Hebert, Thanks for the feedback but what filters , I mean Band pass filters with different cuttoff frequencies and all in a parallel with the Intermediate frequency output ? FFT I can do with 8051 it will require lot of processing power , I need an analog solution ,zero cross detector etc to finally count the frequency output from various filters .
---------------- Do you need to do this in real time? How long do you have to ---detect and do something with the signals? ----------------------------- Yes in real time , The control system should respond in few seconds not a critical process . AP |
