    API's 500-series modules include the 512C preamplifier, the 525 compressor, the 527 compressor, the 550A and 550B semi-parametric equalizers, and the 560 graphic equalizer. [ 2 ] In the mid-1970s, some recording engineers began removing individual processor modules from API mixing consoles and installing them into homemade mounting systems.

    It is also referred to as the sender–message–channelreceiver model, the SMCR model, and Berlo's model. It was first published by David Berlo in his 1960 book The Process of Communication. It contains a detailed discussion of the four main components of communication: source, message, channel, and receiver. Source and receiver are usually ...

  7. Universal asynchronous receiver-transmitter - Wikipedia

    en.wikipedia.org/wiki/Universal_asynchronous...

    At the end of each data frame, the receiver stops briefly to wait for the next start bit. It is this difference that keeps the transmitter and receiver synchronized. BCLK = Base Clock. A UART frame consists of five elements: Idle (logic high (1)) Start bit (logic low (0)): the start bit signals to the receiver that a new character is coming.

  8. Transponder (satellite communications) - Wikipedia

    en.wikipedia.org/wiki/Transponder_(satellite...

    A communications satellite's transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. [1] It is mainly used in satellite communication to transfer the received signals. A transponder is typically composed of: an input band-limiting device (an input band-pass filter),

  9. Relay channel - Wikipedia

    en.wikipedia.org/wiki/Relay_channel

    A discrete memoryless single-relay channel can be modelled as four finite sets, ,,, and , and a conditional probability distribution (, |,) on these sets. The probability distribution of the choice of symbols selected by the encoder and the relay encoder is represented by p ( x 1 , x 2 ) {\displaystyle p(x_{1},x_{2})} .
