Claims (1)

В схеме обработки сигнала, содержащей по меньшей мере два каскада частотной модуляции и демодуляции сигналов, поданных извне или генерируемых внутри этой схемы, модулирующий и демодулирующий сигнал для каждого каскада является эффективно прямоугольным напряжением, при этом отношение частот (F1, F2) модулирующих сигналов для первого и второго каскадов практически соответствует отношению четного целого числа к нечетному целому числу или наоборот, так что практически нет общих частот или гармоник между первым и вторым модулирующими сигналами.In a signal processing circuit containing at least two cascades of frequency modulation and demodulation of signals fed from outside or generated inside this circuit, the modulating and demodulating signal for each stage is effectively a square voltage, and the ratio of the frequencies (F1, F2) of the modulating signals for the first and the second stage practically corresponds to the ratio of an even integer to an odd integer or vice versa, so that there are practically no common frequencies or harmonics between the first and second modulating signal E.
