Single-sideband modulation and its measurement
The most basic form of amplitude modulation is known as double-sideband AM, so called because mirror-image sidebands are produced above and below the carrier frequency. Early researchers found that they could use simple band-pass filters to eliminate one of the sidebands and even the carrier signal, improving the ratio of information-bearing power to total transmitted […]
