How to demodulate an SSB signal?
There are four ways to demodulate a transmitted single sideband (SSB) signal. Those four methods are: synchronous detection, • phasing method, • Weaver method, and • filtering method.
What is demodulating a signal?
Demodulation is extracting the original information-bearing signal from a carrier wave. A demodulator is an electronic circuit (or computer program in a software-defined radio) that is used to recover the information content from the modulated carrier wave.
What is upper sideband and lower sideband?
The sidebands comprise all the spectral components of the modulated signal except the carrier. The signal components above the carrier frequency constitute the upper sideband (USB), and those below the carrier frequency constitute the lower sideband (LSB). All forms of modulation produce sidebands.
What is sideband in amplitude modulation?
Sideband. SIDEBAND. A FREQUENCY component in a SPECTRUM produced by a MODULATION of the original SIGNAL. In the case of amplitude and frequency modulation, sidebands occur in pairs on either side of the CARRIER frequency at a distance equal to the modulating frequency.
