The regenerator is used in the communications, computing andradiomeasuring engineering and in telecontrol. It has increasedfast operation, steepness of the fronts of the initial response,extended frequency range and long-time stability. The regeneratorcontains, connected in series, frequence selective four-pole unit(1), multiphase rectifier (2), emitter repeater (3) and thresholdunit (4). The output of rectifier (2) is connected to one of theleads of capacitor (5) and one of the outputs of an electronicswitch (6). Inverters (7', 7", 7N) matching in numbere the phasesof the multiphase rectifier (2) are connected between the outputof the selective four-pole unit (1) and the inputs of rectifier(2). Unit (4) is made of a threshold element (8) the output ofwhich is connected to the control inputs of three switch elements(9, 10, 11). The output of the first element (9) is connected tothe second lead of capacitor (5), the output of the second element(10) - to the control input of electronic switch (6), and theoutput of the third element (11) is the output of the regenerator.It is also possible that the output of the four-pole unit (1),instead across first inverter (7'), should be directly connectedto the first input of recrifier (2).2 claims, 2 figrues
