Automatic Gain Control in Compact Spectrometers.
Protopopov V. Protopopov V. Appl Spectrosc. 2016 Mar;70(3):539-42. doi: 10.1177/0003702815626683. Epub 2016 Jan 25. Appl Spectrosc. 2016. PMID: 26810181
This opens the possibility of an automatic gain control, a new feature in spectroscopy. With it, the user is relieved from the necessity to manually adjust signal level at a certain value that it is done automatically by means of an electronic feedback …

How much do we gain by gain control in hearing aids?
Moore BC. Moore BC. Acta Otolaryngol Suppl. 1990;469:250-6. Acta Otolaryngol Suppl. 1990. PMID: 2192532 Review.
This paper considers three rationales for the use of automatic gain control (AGC) in hearing aids, and particularly multi-channel AGC. ...To reduce spectral and temporal distortions introduced by the syllabic compression, the number of bands should be small ( …

Comparison of dual-time-constant and fast-acting automatic gain control (AGC) systems in cochlear implants.
Boyle PJ, Büchner A, Stone MA, Lenarz T, Moore BC. Boyle PJ, et al. Int J Audiol. 2009 Apr;48(4):211-21. doi: 10.1080/14992020802581982. Int J Audiol. 2009. PMID: 19363722
Cochlear implants usually employ an automatic gain control (AGC) system as a first stage of processing. AGC1 was a fast-acting (syllabic) compressor. AGC2 was a dual-time-constant system; it usually performed as a slow-acting compressor, but incorporat …

Application of automatic gain control for radiometer diagnostic in SST-1 tokamak.
Makwana FR, Siju V, Edappala P, Pathak SK. Makwana FR, et al. Rev Sci Instrum. 2017 Dec;88(12):124703. doi: 10.1063/1.4994126. Rev Sci Instrum. 2017. PMID: 29289156
This paper describes the characterisation of a negative feedback type of automatic gain control (AGC) circuit that will be an integral part of the heterodyne radiometer system operating at a frequency range of 75-86 GHz at SST-1 tokamak. The developed AGC cir …

The effect of automatic gain control structure and release time on cochlear implant speech intelligibility.
Khing PP, Swanson BA, Ambikairajah E. Khing PP, et al. PLoS One. 2013 Nov 28;8(11):e82263. doi: 10.1371/journal.pone.0082263. eCollection 2013. PLoS One. 2013. PMID: 24312408 Free PMC article.
Nucleus cochlear implant systems incorporate a fast-acting front-end automatic gain control (AGC), sometimes called a compression limiter. ...The envelope profile limiter was located after the filter bank and reduced the gain when the largest of …

A comparison of four methods of implementing automatic gain control (AGC) in hearing aids.
Moore BC, Glasberg BR. Moore BC, et al. Br J Audiol. 1988 May;22(2):93-104. doi: 10.3109/03005368809077803. Br J Audiol. 1988. PMID: 3390637
To ensure that low-level sounds can be heard, while avoiding discomfort at high levels, a hearing aid with automatic gain control (AGC) is required. This paper compares four different systems for implementing AGC, and compares each of them with unaided listen …

Listening to Music Through Hearing Aids: Potential Lessons for Cochlear Implants.
Moore BCJ. Moore BCJ. Trends Hear. 2022 Jan-Dec;26:23312165211072969. doi: 10.1177/23312165211072969. Trends Hear. 2022. PMID: 35179052 Free PMC article.
In HAs, this is usually done via multi-channel amplitude compression (automatic gain control, AGC). In CIs, a single-channel front-end AGC is applied to the broadband input signal or a control signal derived from a running average of the broadband sign …
