Abstract
Mejoras en sistemas de demodulación de una onda modulada por una forma de onda de señal que esencialmente se repite a una frecuencia predeterminada, en los que la onda de señal (detectada o no) y una onda derivada localmente de la misma frecuencia y preferiblemente de la misma forma que la onda de señal son respectivamente aplicadas a dos circuitos de entrada de un detector diferencial o modulador equilibrado.Improvements in systems for demodulation of a waveform modulated by a signal waveform essentially repeating at a predetermined frequency, in which the signal wave (detected or not) and a locally derived wave of the same frequency and preferably from the The same shapes as the signal waveform are respectively applied to two input circuits of a differential detector or balanced modulator.
