... white of 1 volt, blanking occurs at 0.3 volt (see fig. 1). If the maximum amplitude of the RF carrier is taken to be 1.0, then the amplitude can vary from 1.0 to 0.1; that is, a range of 0.9. Multiplying 0.3 and 0.9 we obtain 0.27, so that blanking represents an RF carrier level of (1.0 – 0.27) = 0. ...

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.
