sorry for failure to spell check hourse = noise simply = simple

Thanks very much for your replies! The signal I am transducing is surprisingly enough, a harmonica reed. I'm relatively sure of the horse source as I experimented with an isolated sensor with just a pull up resistor, illuminated by mini incandescent light. I've tried a compressor but was...

Citizens of Eng-tips. I would really appreciate your advice. I've been wrestling with a pesky noisy phototransistor for quite a long time, and am at wit's end. The sensor is being used to transuce an audio signal in the 1-5kHz range. Unfortunately the shot noise is introducing a broadband...

Thanks everyone for your help. I myself havent cracked open Ashby's in a long time... and will give this a try. Much obliged.

I am seeking a spring alloy in sheet form with minimal damping. It musth sustain vibration for a long period of time once initially struck or plucked. I cannot find the proper specificiation, but perhaps loss coefficient, or loss tangent, of coefficient of restitution is close. Nevertheless I...
