audio bandwidth
51AM stereo — is a term given to a number of mutually incompatible techniques for broadcasting stereo audio in the AM band in a manner that is compatible with standard AM receivers. There are two main classes of systems: independent sideband (ISB) systems,… …
5280-meter band — The 80 meter or 3.5 MHz band is a core amateur radio frequency band, allocated frequencies from 3.5 to 4.0 MHz in IARU Region 2, and generally 3.5 to 3.8 or 3.9 MHz in Regions 1 and 3 respectively. The portion of the band used for voice… …
53AM broadcasting — is the process of radio broadcasting using amplitude modulation.HistoryAM was the dominant method of broadcasting during the first eighty years of the 20th century and remains widely used into the 21st.AM radio began with the first, experimental… …
54G.722.1 — is a licensed royalty free ITU T standard audio codec providing high quality, moderate bit rate (24 and 32 kbit/s) wideband (50 Hz 7 kHz audio bandwidth, 16 ksps) audio coding. It is an implementation of Polycom s SIREN7 codec.G.722.1 is the… …
55Ambisonic UHJ format — is a development of the Ambisonic surround sound system designed to allow Ambisonic recordings to be carried by mono and stereo compatible media. It is a hierarchy of systems in which the recorded soundfield will be reproduced with a degree of… …

57High fidelity — or hi fi reproduction is a term used by home stereo listeners and home audio enthusiasts (audiophiles) to refer to high quality reproduction of sound or images that are very faithful to the original master recording. High fidelity equipment has… …
58HE-AAC — High Efficiency AAC (HE AAC) is a lossy data compression scheme for digital audio. It is an extension of Low Complexity AAC (AAC LC) optimized for low bitrate applications such as streaming audio. HE AAC version 1 (HE AAC v1) uses spectral band… …
59Radio transmitter design — In plate modulation systems the voltage delivered to the stage is changed. As the power output available is a function of the supply voltage, the output power is modulated. This can be done using a transformer to alter the anode (plate) voltage.… …
