Abstract
Изобретениеможет быть использовано дл усилени по мощности напр жени низкой чистоты. Цель изобретени - уменьшение коэф. нелинейных искажений. Входной сигнал поступает через интегратор 1 на релейный элемент 2 и сумматор 5. На вход управл емого элемента задержки ( УЭЗ ) 3 от cyMMaTopia 5 одновременно с выходными импульсами релейного элемента 2 поступает напр жение, определ ют щее изменение пол рности выходного напр жени УЭЗ 2. Это зависит от величины усиливаемого сигнала, поступающего с входа усилител класса Д через сумматор 5 на вход УЭЗ. Выходные 1О4пульсы УЭЗ задерживаютс S на интервалы, цропорциональные величине усиливаемого сигнала, что позвол ет уменьшить нелинейные искажени . 2 ил.The invention can be used to increase the power of a low-purity voltage. The purpose of the invention is to reduce the coefficient. nonlinear distortion. The input signal is fed through the integrator 1 to the relay element 2 and the adder 5. The input of the controlled delay element (UES) 3 from cyMMaTopia 5 simultaneously with the output pulses of the relay element 2 receives a voltage, which determines the polarity of the output voltage of the UES 2. It depends on the magnitude of the amplified signal coming from the input of the class D amplifier through the adder 5 to the input of the UEZ. UZZ output pulses are delayed by S at intervals that are proportional to the magnitude of the signal being amplified, thereby reducing nonlinear distortion. 2 Il.
