... Illustration: Does homogenity hold for the following equation? Given, y = 4x Eq 9.1 If x = 1, y = 4. If we double x to x = 2 and substitute this value into Eq 9.1 we get y = 8. Now for homogenity to hold, scaling should hold for y. that is, y has a value of 4 when x = 1. If we increase x by a factor ...

Opto-isolator



In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators withstand input-to-output voltages up to 10 kV and voltage transients with speeds up to 10 kV/μs.A 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.
