Re: Knock Sensor Circuit Design ...	Tue, 22 July 2003 08:10

you can easily make high and low pass filters using resistor and capacitors http://www.phys.unsw.edu.au/~jw/RCfilters.html try various combinations on the input signal. if the signal is too low you could put a small gain (maybe x10) on the input to bump it up before filtering. 1N914 info http://www.fairchildsemi.com/ds/1N/1N914.pdf isn't the 0.01uf cap providing filtering after the diode?
