WebJan 31, 2003 · Audio Signal Isolation Techniques - Analog Optocouplers Sometimes it desirable to isolate analog signals. This can be done in some different ways. We can use separate power supplies for the source and the receiver. But then we still have a common earth rail. This rail can transmitt disturbance, noise, hum and distort the signal. something about pacmanWebA common type of opto-isolator consists of an LED and a phototransistor in the same opaque package. Other types of source-sensor combinations include LED-photodiode, LED-LASCR, and lamp-photoresistor pairs. Usually opto-isolators transfer digital (on-off) signals, but some techniques allow them to be used with analog signals.
