... Chaos, along with Quantum Mechanics and Relativity, has been hailed as one of the major discoveries of 20th century. Chua’s circuit was the first circuit implementation specially designed to exhibit chaos [Chua, 1984] and the first that was proved to be chaotic rigorously [Chua, et. al. 1986]. Chua’ ...

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.
