Track while scan. Track-while-scan ( TWS) is a mode of radar operation in which the radar allocates part of its power to tracking a target or targets (up to forty with modern radar) while part of its power is allocated to scanning. It is similar to but functions differently in comparison to its counterparts range-while-search (RWS), long range ...
Project 25 ( P25 or APCO-25) is a suite of standards for interoperable digital two-way radio products. P25 was developed by public safety professionals in North America and has gained acceptance for public safety, security, public service, and commercial applications worldwide. [1] P25 radios are a direct replacement for analog UHF (typically ...
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 ). In this example, a signal received by the microphone is amplified and passed out ...
The active input is showing full gain with a ladder of green LEDs. An automixer, or automatic microphone mixer, is a live sound mixing device that automatically reduces the strength of a microphone 's audio signal when it is not being used. Automixers reduce extraneous noise picked up and comb filtering effects when several microphones operate ...
Automatic gain control. Schematic of an AGC used in the analog telephone network; the feedback from output level to gain is effected via a Vactrol resistive opto-isolator. Automatic gain control ( AGC) is a closed-loop feedback regulating circuit in an amplifier or chain of amplifiers, the purpose of which is to maintain a suitable signal ...
This sweet and expressive Bernedoodle is a family gal through and through, and she's always enjoying time with her human parents and Pug sister. When they showed her a harmonica for the first time ...

Noise control is an active or passive means of reducing sound emissions, often for personal comfort, environmental considerations, or legal compliance. Active noise control is sound reduction using a power source. Passive noise control is sound reduction by noise-isolating materials such as insulation, sound-absorbing tiles, or a muffler rather ...
