AM Modulator - PCOM

AM Modulator Types of AM modulator There are low-level and high-level modulators.

Low-level modulators generate AM with small signals and must be amplified before transmission.

High-level modulators produce AM at high power levels, usually in the final amplifier stage of a transmitter.

Low level modulator

Low level modulator waveforms Collector modulated Class C amplifier

Collector Bias Carrier Wave

Output at collector (without tank circuit)

AM waveform due to flywheel

Balanced Modulator A balanced modulator is a circuit that generates a DSB signal, suppressing the carrier

and leaving only the sum and difference frequencies at the output.
