73C-MAC — is the variant approved by the European Broadcasting Union (EBU) for satellite transmissions. The digital information is modulated using 2 4PSK (phase shift keying), a variation of quadrature PSK where only two of the phaser angles (±90°) are… …
74Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… …
75Radio 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.… …
