Distortion. In signal processing, distortion is the alteration of the original shape (or other characteristic) of a signal. In communications and electronics it means the alteration of the waveform of an information-bearing signal, such as an audio signal representing sound or a video signal representing images, in an electronic device or ...
Transimpedance amplifier. Fig. 1. Simplified transimpedance amplifier. In electronics, a transimpedance amplifier (TIA) is a current to voltage converter, almost exclusively implemented with one or more operational amplifiers. The TIA can be used to amplify [1] the current output of Geiger–Müller tubes, photo multiplier tubes, accelerometers ...
Yorkville Sound. Yorkville Sound is a Canadian manufacturer of audio amplifiers (including the Traynor amplifier line), loudspeakers and related professional sound reinforcement equipment. [1] [2] Based in Pickering, Ontario, Canada, the firm has a global presence as an importer and exporter of audio electronic products. [3][4]
James M. Williams (April 14, 1948 – June 12, 2011) was an analog circuit designer and technical author who worked for the Massachusetts Institute of Technology (1968–1979), Philbrick, National Semiconductor (1979–1982) and Linear Technology Corporation (LTC) (1982–2011). [1] He wrote over 350 publications [2] relating to analog circuit ...
Tube sound (or valve sound) is the characteristic sound associated with a vacuum tube amplifier (valve amplifier in British English), a vacuum tube -based audio amplifier. [1] At first, the concept of tube sound did not exist, because practically all electronic amplification of audio signals was done with vacuum tubes and other comparable ...
The Doherty amplifier is a modified class B radio frequency amplifier invented by William H. Doherty of Bell Telephone Laboratories Inc in 1936. Whereas conventional class B amplifiers can clip on high input-signal levels, the Doherty power amplifier can accommodate signals with high peak-to-average power ratios by using two amplifier circuits within the one overall amplifier to accommodate ...
A digitally controlled amplifier (DCA) is a variable-gain amplifier that is digitally controlled. The digitally controlled amplifier uses a stepped approach giving the circuit graduated increments of gain selection. This can be done in several fashions, but certain elements remain in any design.
Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. [1][2] Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments.
