The circuit was designed to produce a 500mW output power transmitter whose signal modulated by FM using four transistors. Transmitter – an electronic device that can produce or amplify a carrier wave ...
NBFM or Narrow Band Frequncy Modulation is used in this 27 MHz transmitter circuit schematic. This circuit is an application by Motorola MC2833 – VHF transmitter with FM modulation and narrow band in ...
The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...
