FIELD: electricity. ^ SUBSTANCE: control device of amplitude of heavy signals includes the first low-pass filter the input of which is the input of device for controlled signal, the second low-pass filter the output of which is the output of device, bipolar transistor the emitter of which is connected to input of the second low-pass filter, resistor and input of control signal. There introduced is semiconductor diode the first output of which is connected to base of bipolar transistor, and the second output is connected to input of control signal, and additional bipolar transistor the emitter of which is connected to output of the first low-pass filter, collector - to base of bipolar transistor, and base - to the first output of resistor; at that, collector of bipolar transistor is connected to output of the first low-pass filter and the second output of resistor is connected to common conductor. ^ EFFECT: creation of control device of amplitude of heavy pulse signals, which is capable of operating from heavy pulse generator, both with low and high output resistance. ^ 3 dwg |
