101Maximum usable frequency — (MUF) describes, in radio transmission, using reflection from the regular ionized layers of the ionosphere, the upper frequency limit that can be used for transmission between two points at a specified time, independent of transmitter power. This …
102Voice frequency — A voice frequency (VF) or voice band is one of the frequencies, within part of the audio range, that is used for the transmission of speech. In telephony, the usable voice frequency band ranges from approximately 300 Hz to 3400 Hz. It is for this …
103Mel-frequency cepstrum — In sound processing, the mel frequency cepstrum (MFC) is a representation of the short term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency. Mel frequency cepstral… …
104Gold standard (test) — For other uses, see Gold standard (disambiguation). In medicine and statistics, gold standard test refers to a diagnostic test or benchmark that is the best available under reasonable conditions. It does not have to be necessarily the best… …
105Superconducting Radio Frequency — (SRF) science and technology involves the application of electrical superconductors to radio frequency devices. The ultra low electrical loss of the superconductor yields RF resonators with extremely high quality factors, or Q . For example, it… …

109Australian Fair Pay and Conditions Standard — The Australian Fair Pay and Conditions Standard (the Standard) is a set of five minimum statutory entitlements for wages and conditions that was introduced as part of the Howard Government s WorkChoices amendments to Australian labour law. It… …
110Critical frequency — In telecommunication, the term critical frequency has the following meanings: In radio propagation by way of the ionosphere, the limiting frequency at or below which a wave component is reflected by, and above which it penetrates through, an… …
