  2. Audio-to-video synchronization - Wikipedia

    en.wikipedia.org/wiki/Audio-to-video_synchronization

    The AV-sync delay is static but can vary with the individual clip. Video editing effects can delay video causing it to lag the audio. Transmission (broadcasting), reception and playback that can get introduce AV-sync errors. A video camera with built-in microphones or line-in may not delay sound and video paths by the same amount.

  3. Radio noise - Wikipedia

    en.wikipedia.org/wiki/Radio_noise

    Radio noise near in frequency to a received radio signal (in the receiver's passband) interferes (RFI) with the operation of the receiver's circuitry.The level of noise determines the maximum sensitivity and reception range of a radio receiver; if no noise were picked up with radio signals, even weak transmissions could be received at virtually any distance by making a radio receiver that had ...

    In satellite communications, carrier-to-noise-density ratio (C/N 0) is the ratio of the carrier power C to the noise power density N 0, expressed in dB-Hz.When considering only the receiver as a source of noise, it is called carrier-to-receiver-noise-density ratio.
