3rd Enigma Posted February 9, 2004 Share Posted February 9, 2004 Hey, I getting ready to start my next major project in my electronics program and I would like to ask some opinion on how a good laser audio ear would be made. Having efficient laser receptor (emitter is a cheap laser pointer) and good gain on the output to be used by a variety of speakers. !NOTE! I am asking for hints to improve circut not necessaily making it. Link to comment Share on other sites More sharing options...
YT2095 Posted February 9, 2004 Share Posted February 9, 2004 a good bandpass filter would be a good idea too, it`ll help filter out any rumble at the low end and hiss at the top end that a laser reflection is likely to pick up. 300 hz to about 4khz sould be a nice workable range Link to comment Share on other sites More sharing options...
