They can result from improper clock sources [3] and buffer size. Also, clicks can be caused by electric devices near the computer or by faulty audio or mains cables. [4] In sample recording, digital clicks occur when the signal levels of two adjacent audio sections do not match. The abrupt change in gain can be perceived as a click. [5]
These can manifest only at specific environmental conditions, high clock speeds, low power supply voltages, and sometimes specific circuit signal states; significant variations can occur on a single die. [9] Overstress-induced damage like ohmic shunts or a reduced transistor output current can increase such delays, leading to erratic behavior.
Memory effect, also known as battery effect, lazy battery effect, or battery memory, is an effect observed in nickel-cadmium rechargeable batteries that causes them to hold less charge. [ 1 ] [ 2 ] It describes the situation in which nickel-cadmium batteries gradually lose their maximum energy capacity if they are repeatedly recharged after ...
Electromagnetic interference divides into several categories according to the source and signal characteristics. The origin of interference, often called "noise" in this context, can be human-made (artificial) or natural. Continuous, or continuous wave (CW), interference arises where the source continuously emits at a given range of frequencies.
In many cases noise found on a signal in a circuit is unwanted. There are many different noise reduction techniques that can reduce the noise picked up by a circuit. Faraday cage – A Faraday cage enclosing a circuit can be used to isolate the circuit from external noise sources. A Faraday cage cannot address noise sources that originate in ...
Block diagram of the signal-flow for a common feedback loop [1]: 118 . Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup).

This is the ratio (usually expressed in dB) between the noise floor of the device with no signal and the maximum signal (usually a sine wave) that can be output at a specified (low) distortion level. Since the early 1990s it has been recommended by several authorities including the Audio Engineering Society that measurements of dynamic range be ...
