What is signal attenuation? - Analog IC Tips

Attenuation (dB)= 10 X log (PI/PO) Where P I is input power and P O is the output power. P I is the power applied at one end of the cable, while P O is …
What is "Attenuation"?
https://www.sweetwater.com/insync/attenuation/
A decrease in the level of a signal is referred to as attenuation. In some cases this is unintentional, as in the attenuation caused by using wire for signal transmission. Attenuators (circuits which attenuate a signal) may also be used to lower the level of a signal in an audio system to prevent overload and distortion.
Homemade RCA Attenuator : 5 Steps (with Pictures ...

Before proceeding further, we have to remember that the audio signal can be distinguished substantially in two categories: . 1) balanced circuit. 2) unbalanced circuit. The main difference between the two is that one is represented by an unshielded cable while the other does not. However, in reality the common RCA cable we use every day is made ...
Notes on Audio Attenuators - Tangentsoft

With potentiometer type attenuators, the tracking spec will only be given down to a certain level. A common spec is 3 dB down to -40 dB. 40 dB is a factor of 100, so such a pot is guaranteed to have its channels within 3 dB of each other down to the point where the pot is attenuating the signal to 0.01×.

Connect the bypass pin of the amplifier IC to the low end of the volume control with U9B removed. The 1uF bypass filter capacitor is a low impedance to audio frequencies and the bias current of the MCP6L01 or MCP6L02 opamp is extremely low.

An amplifier may include two or more pulse-width modulators (PWMs) controlling respective sets of switches to produce an amplified version of a source signal. The clocking for the amplifier may be controlled to delay signal processing within the PWMs relative to one another in time, thereby providing an effective time offset between the respective edge transitions of the controlling …
Tutorial: Basic Volume Control [Analog Devices Wiki]

Changing the volume or amplitude of the audio signal passing through the SHARC Audio Module requires us to simply multiply each sample by a constant value. If that value is between 0.0 and 1.0, the volume will be decreased, or “attenuated”. If the value is greater than 1.0, the volume will be increased, or “amplified”.
The Complete Guide to Audio Compression – Icon …

The threshold control sets the dB level where the audio signal has to exceed for the compression to activate. Any signal that passes above the threshold gets compressed. Furthermore, a lower threshold will reduce a greater portion of the signal. Whereas, a higher threshold will reduce only the loudest peaks and leave the rest untouched. Ratio
