MPX Filter
MPX filter is a function found in analogue stereo FM broadcasting and personal monitor equipment, FM tuners and cassette decks. An MPX filter is, at least, a notch filter blocking the 19 kHz pilot tone, and possibly higher frequencies in the 23-53kHz and 63-75kHz bands. Broadcasting and personal monitors FM stereo broadcasts contain a ''pilot tone'' - a 19 kHz sinewave serving as a phase reference for decoding the stereophonic information. The system was developed jointly by Zenith and General Electric, and approved by the FCC in 1961. Normal monaural audio, the pilot tone and the double sideband stereophonic difference information are all mixed together into composite FM baseband signal extending to 53 kHz (stereo audio only) or 99 kHz (stereo audio plus an auxiliary subchannel, so-called ''SCA''). The process of encoding the difference signal into the 23-53kHz band via double-sideband carrier-suppressed amplitude modulation is an instance of multiplexing (hence the name '' ...

Multiplexing
In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share a scarce resource—a physical transmission medium. For example, in telecommunications, several telephone calls may be carried using one wire. Multiplexing originated in telegraphy in the 1870s, and is now widely applied in communications. In telephony, George Owen Squier is credited with the development of telephone carrier multiplexing in 1910. The multiplexed signal is transmitted over a communication channel such as a cable. The multiplexing divides the capacity of the communication channel into several logical channels, one for each message signal or data stream to be transferred. A reverse process, known as demultiplexing, extracts the original channels on the receiver end. A device that performs the multiplexing is called a multiplexer (MUX), and a ...

Multiplexer
In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several Analog signal, analog or Digital signal (electronics), digital input signals and forwards the selected input to a single output line. The selection is directed by a separate set of digital inputs known as select lines. A multiplexer of 2^n inputs has n select lines, which are used to select which input line to send to the output. A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal. Multiplexers can also be used to implement Boolean algebra, Boolean functions of multiple variables. Conversely, a demultiplexer (or demux) is a device that takes a single input signal and selectively forwards it to one of several output lines. A multiplexer is often used with a complem ...
