Abstract
Circuit for analyzing an amplitude-modulated electric signal. This circuit comprises a quartz oscillator operating at a frequency fq, a frequency transposer making it possible to transpose the spectrum of the incident signal about fq, a narrow filter centered on one of the side bands, a detector receiving said side band and the reference signal at frequency fq and two processing channels, one being an amplitude channel and the other a phase channel. Application of the measurement of the current in an antenna, to the characteristics of quadripoles, impedances, etc.
