How Single-Sideband Transmitters Work

This lesson explains how a single-sideband (SSB) radio turns your voice into a radio signal, step by step. You will learn the specific job of each component, from the microphone to the final amplifier.

This lesson is part of SignalPrep Pro. The subsection's 9 exam questions are free to practise: practise B-003-006.
