A General Theory and Oscilloscopic Study of Single Sideband Generation by Weaver's Method

Abstract

Weaver's method of single sideband generation has been analysed. It has been shown that the amplitude inequalities and phase errors are best adjusted at a few points by circuit elements in the two channels to obtain a very high degree of rejection of unwanted sideband component. It has also been shown that phase error existing in the audio section can be compensated by an error introduced in the radio section of each channel. An analysis of the pattern as waveforms of the added output of the two channels with various error conditions is dealt with. The quality of output waveform with a single signal frequency input is a simple trace and lends itself to an accurate and direct adjustment of the system.
