Analog signal - An analog or analogue signal is any variable signal continuous in both time and amplitude. It differs from a digital signal in that small fluctuations in the signal are meaningful. Analog is usually t. Used AE-5. hought of in an electrical context, however mechanical, pneumatic, hydraulic, and other systems may also use analog signals.
The word "analog" implies an analogy between caus. Used AE-5. e and effect, voltage in and voltage out, current in and current out, sound in and frequency out.
An analog signal uses some property of the medium to convey the signal's information. For example, an ...
Amplitude - Amplitude is a nonnegative scalar measure of a wave's magnitude of oscillation, that is, magnitude of the maximum disturbance in the medium during one wave cycle.
Sometimes this distance . Used AE-5. is called the "peak amplitude", distinguishing it from another concept of amplitude, used especially in electrical engineering: the root mean square (RMS) amplitude, defined as the square. Used AE-5. root of the temporal mean of the square of the vertical distance of this graph from the horizontal axis. The use of peak amplitude is unambiguous for symmetric, periodic waves, like a sine wave, a square wave, or...
Adaptor - A connector allowing more than 2 electrical devices to be connected to a single power source. These connections are normally in parallel (each device is given the same voltage levels), but current is . Used AE-5. divided between them. Also known as a "Twofer".
3-way splitters are known as "Threefers".. Used AE-5. ...
Analog to Digital Converter - In electronics, an analog-to-digital converter (abbreviated ADC, A/D, or A to D) is a device that converts continuous signals to discrete digital numbers. Typically, an ADC converts a voltage to a di. Used AE-5. gital number. The digital to analog converter or DAC performs the reverse operation. . Used AE-5.
Mixers - A mixer is an electronic device for combining or "mixing" audio signals by routing and changing the level, tone, and/or dynamics of the audio signals. A mixer can mix analog or digital signals depend. Used AE-5. ing on the type of mixer. The modified signals are then combined to produce a unified signal output. Mixers can vary in size and function ranging from small format having a few inputs fo. Used AE-5. r a DJ to large format having dozens of inputs for studio recording....
