In radio, an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.[1] In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves. Determination and Classification of Coverage Areas of Terrestrial UHF Television Transmitters inOndo State, Nigeria. 1*Akinbolati, much work had been done on the A.M radio signals in this regard [1] being the first generation radio stations in Nigeria [2]. transmitter-receiver distance, transmitter power [9] and others like, terrain.

Voice Operation of Transmitters There are three common voice modes for Amateur Radio — AM (amplitude modula- tion), SSB (single-sideband) and FM (fre- quency modulation). AM was the popular mode used in the early days of radio, and remains the method used in the standard broadcast band covering to kHz. For radio telephone working over long distances on short waves, highly directive transmitting and receiving antennas are used so that carrier power required may be relatively small; of the order of 5 kW or so. Block diagram of AM transmitter. AM Transmitter: Transmitters that transmit AM signals are known as AM transmitters. LECTURE ON AM/FM TRANSMITTER. CLASSIFICATION BASED ON TYPES OF MODULATION  CW Transmitters  AM Transmitters  FM Transmitters  SSB Transmitters Punjab Edusat Society. CONTINIOUS WAVE (CW) TRANSMITTERS  The CW Transmitter is the simplest type of transmitter.  It is a simple crystal oscillator circuit.few microseconds to tens of milliseconds. The analysis and classification of radio transmitters have been reported in [1]-[8]. The transient signals were acquired. When a radio transmitter is engaged for transmission after the push-to-talk button is pressed, it is observed that its transient behavior i.e. RF power and carrier.
