TIME INTERVAL VOLTAGE CONVERTER

摘要

The proposed converter consists of a pulse generator (1) connected to a pulse counter (2) whose outputs enter the inputs of the decoders (3 and 4). A short pulse from the output of the decoder (4) enters the control input of the switch (11) whose signal input is connected to the output of the controlled current generator (6), the sensor (8) and one input of the differential amplifier (7). The output of the switch (11) is connected to an analogue memory unit (10) whose output voltage is the reference for the functional converter (5) and comparator (9). A long pulse from the output of the decoder (3) enters the input of the functional converter (5) where it is converted into voltage of a particular form in accordance with the set program and enters the input of the controlled current generator (6) which forms a current at its output in accordance with the function of the functional converter (5). The signal from the output of the differential amplifier (7), whose inputs are connected to the outputs of the functional converter (5) and sensor (8), enters the signal input of the comparator (9) at whose output is formed a time interval corresponding to the dynamic magnitude of the effect of external factors on the sensor (8). The input of the voltage repeater (12) is connected to the output of the memory unit (10), and at the output of the voltage repeater (12) a voltage is formed corresponding to the static parameter of the sensor (8).
