Description

(54) УСИЛИТЕЛЬ С УПРАВЛЯЕМЫМ КОЭФФИЦИЕНТОМ ПЕРЕДАЧИ(54) AMPLIFIER WITH CONTROLLED TRANSFER COEFFICIENT

низкочастотным управл ющим сигналом. Антилогарифмический преобразователь 2 формирует сигнал, содержащий посто нную составл ющую и высокочастотную составл квдую,. пропорциональную отношению высокочастотной составл ющей суммарного сигнала на входе усилител  к низкочастотной.low frequency control signal. The anti-log converter 2 generates a signal containing a constant component and a high frequency component. proportional to the ratio of the high-frequency component of the total signal at the input of the amplifier to the low-frequency one.

Второй фильтр 4 высоких частот пропускает высокочастотную составл ющую . На выходе усилител  формируетс  сигнал, пропорциональный отношению усиливаемого и управл квдего сигналов.The second high-pass filter 4 passes the high frequency component. At the output of the amplifier, a signal is generated that is proportional to the ratio of the signal being amplified and controlled.

Изменение коэффициента передачи усилител  достигаетс  изменением управл ющего сигнала.A change in the gain of the amplifier is achieved by changing the control signal.

Таким образом, благодар  введению двух фильтров высоких Частот исключают один из логарифмических преобразователей и сумматор, что упрощает функциональную схему устройства и уменьшает трудоемкость его настройки .Thus, due to the introduction of two high-frequency filters, one of the logarithmic converters and an adder are eliminated, which simplifies the functional diagram of the device and reduces the complexity of its configuration.
