Audio Signal - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/engineering/audio-signal
The processing of video signals is, however, significantly different than audio as the amount of information for video signals is magnitudes greater than that of audio. Video processing may involve amplifying or adjusting the timing, color, brightness, or contrast of the signal. Video processing equipment can include time base correctors to maintain the integrity of the signal …
AUDIO AND VIDEO SIGNAL GENERATORS
https://electriciantraining.tpub.com/14188/css/Audio-And-Video-Signal-Generators-146.htm
VIDEO SIGNAL GENERATORS produce signals that include the audio range and extend into the rf range. These signal generators are used to test video amplifiers and other wideband circuits. In both audio and video signal generators (figure 5-5), major components include a POWER SUPPLY, an OSCILLATOR (or oscillators), one or more AMPLIFIERS, and an OUTPUT CONTROL. Figure 5 …

In IP network monitoring system, between audio and video signals exist interference problems. Although the audio and video signal data in the same IP network to separate the transmission, there is no interference in theory, but in the installation should consider the location of the connection.For example the wiring distance should be with the radio …

A visible light communication system for transmission of audio and video signals employing visible LEDs was presented. The S/PDIF formatted audio signal is digitized and used to intensity-modulate white illumination LEDs. Simultaneously, the analog video signal was transmitted using PWM via red illumination LEDs.
RF Modulation and Demodulation of Audio and Video Signals
https://www.ramelectronics.net/Audio-Video-RF-Modulation-Demodulation.aspx
An analog audio or video signal is a severely modified sign wave. With audio, the frequency denotes the note while the amplitude of the sign wave denotes the volume. With video, the frequency denotes the color, while the amplitude denotes the brightness. That makes it much harder to turn audio and video signals into RF for transmission.

Audio Processing. Steven W. Smith, in Digital Signal Processing: A Practical Guide for Engineers and Scientists, 2003. Audio processing covers many diverse fields, all involved in presenting sound to human listeners. Three areas are prominent: (1) high fidelity music reproduction, such as in audio compact discs, (2) voice telecommunications, another name for telephone networks, …

Figure 2:-10 dBV line level consumer gear vs. +4dBu line level pro audio gear. If you’re working solely with pro audio gear, most of it likely calls for a +4 dBu line level signal, but some pro audio gear might have a switch that allows you swap inputs between a …
