PROBLEM TO BE SOLVED: To provide an amplitude modulation circuit with high efficiency which obtains a stable modulation characteristic even to load fluctuation, especially has almost no possibility of spurious generation and directly controls high frequency power through digital control to perform ...
Pulse Amplitude Modulation (PAM) is defined as the data transmission by altering the amplitudes of every pulse in a regular time sequence of electromagnetic pulses. Learn its circuit and block diagram at BYJU'S.
Amplitude modulation circuit in which a resonant circuit (12) which determines the carrier frequency is connected to the collector of one transistor (T,4) forming the differential pair of a differential amplifier (13) connected on the grounded side to a constant-current source (15), the output...
Modulation frequency response stabilized amplitude modulation circuit A frequency response stabilized amplitude modulation circuit includes a variable gain amplitude modulator (20) producing an output signal (V) of which the amplitude is proportional to the product of the amplitudes of a carrier signal (...
