The Sideband Technique of R-F Wave Analysis
Abstract
A technique for analyzing complex, radio-frequency waves utilizes a visual display of the carrier and sideband components on a cathode-ray oscilloscope. An instrument developed to confirm this technique is described, and some of the developmental problems and operational phenomena are illustrated by oscillograms. The value of such a technique is stressed with regard to spectrum economy, and application of the technique to the problems of intercept and identification is indicated. The analyzer accurately displays relative side-band power and spectrum occupancy and resolves sidebands as low as 20 cycles per second.
