22Output power of an analog TV transmitter — Output power of a TV transmitter is the electric power applied to antenna system. There are two definitions: nominal (or peak) and thermal. Contents 1 Power defined in terms of voltage 2 Nominal power of a TV transmitter 3 The thermal power …
23Broadcast signal intrusion — is a term given to the act of hijacking broadcast signals of radio and television stations. Hijacking incidents have involved local TV and radio stations as well as cable and national networks. Method of intrusion For analog stations it is… …
24Ultra high frequency — (UHF) designates a range (band) of electromagnetic waves with frequencies between 300 MHz and 3 GHz (3,000 MHz). Also known as the decimeter band or decimeter wave as the wavelengths range from ten to one decimeters. Radio waves with frequencies… …
25Very low frequency — or VLF refers to radio frequencies (RF) in the range of 3 kHz to 30 kHz. Since there is not much bandwidth in this band of the radio spectrum, only the very simplest signals are used, such as for radio navigation. Also known as the myriameter… …
26Radio-frequency identification — (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from… …
27Audio signal processing — Audio signal processing, sometimes referred to as audio processing, is the intentional alteration of auditory signals, or sound. As audio signals may be electronically represented in either digital or analog format, signal processing may occur in …
