Dichroic filter — Dichroic filters A dichroic filter, thin film filter, or interference filter is a very accurate color filter used to selectively pass light of a small range of colors while reflecting other colors. By comparison, dichroic mirrors and dichroic… … Wikipedia
Lock-in amplifier — A lock in amplifier (also known as a phase sensitive detector) is a type of amplifier that can extract a signal with a known carrier wave from extremely noisy environment (S/N ratio can be as low as 60 dB or even lessFact|date=December 2007). It… … Wikipedia
Falsing — In telecommunications, falsing describes a decoder detecting a valid input when one is not present. This is also known as a false decode. To make the concepts simpler, this article will discuss analog circuits used before digital signal… … Wikipedia
Radio transmitter design — In plate modulation systems the voltage delivered to the stage is changed. As the power output available is a function of the supply voltage, the output power is modulated. This can be done using a transformer to alter the anode (plate) voltage.… … Wikipedia
