Abstract
Методът и схемата са за измерване характеристиката на изкривяванията на предавателни системи, по-специално при блокове с носеща честота на радиоразпръсквателни релейни системи (схеми с междинна честота и схеми с ниска честота), въз основа на принципа на измерване на диференциалното усилване. През време на продължителността на периода на генератора за опипващи сигнали (g), включен от страна на предавателя, се възбужда повтаряща се носеща вълна, която е модулирана с измервателни сигнали с две различни честоти. От страна на приемника в такта на смяната от страна на предавателя честотата на усилвателя (а) на избирателния измервателен сигнал се превключва на честотата на съответния измервателен сигнал, а усилването се превключва обратно пропорционално на квадрата на отношението на честотите на измервателния сигнал. 2 претенции, 1 фигураThe method and scheme are for measuring the distortion characteristic of transmission systems, in particular in carrier frequency blocks of radio broadcasting relay systems (intermediate frequency circuits and low frequency circuits), based on the principle of differential gain measurement. During the period duration of the probe signal generator (g) switched on by the transmitter, a repeating carrier wave is excited which is modulated with measurement signals of two different frequencies. On the receiver side, on the transmitter side switching clock, the amplifier frequency (a) of the selective measurement signal is switched to the frequency of the corresponding measurement signal, and the gain is switched inversely proportional to the square of the ratio of the measurement signal frequencies. 2 claims, 1 figure
