Description

(54) DEVICE FOR FIXING ELECTRIC

VELICHIN

The input signal may disappear immediately after the amplitude is selected at the output of the amplitude detector 11. In this case, the delay element 4 is held until the delay element 6 is triggered by a signal from the output of the pulse duration limiter 8, whose output signal duration overlaps the time delay of the second delay element 6. The latter, by its disconnecting contact 7, separates the charged sealing capacitor 14 from the input circuit and sends a signal to start up the analog-to-digital converter 15, which converts the voltage on the storage capacitor 14 to the number of pulses counted by the pulse counter 16.

The second delay element 6 is held on the operating time of the analog-to-digital converter 15 (the open state of contact 7 is saved for this time) is carried out by a signal taken from the additional output of the analog-digital

converter 15, which is supplied to the second input of delay element 6.

Thus, the proposed device shortens the required time for an input signal, i.e. possesses increased speed.
