DEVICE FOR MEASURING AND CONTROLLING AMPLITUDE-FREQUENCY CHARACTERISTIC OF QUADRIPOLE Russian patent published in 2005 - IPC

FIELD: amplitude-frequency characteristics of quadripoles.

SUBSTANCE: control of quadripole is realized in two stages. At first stage, estimation stage, N counts of measurements results are received during length T of one signal period, and on second stage, analysis stage, during time T received signal estimation results are recognized with determining of class of technical state of object (like breakdown). To realize first stage of control, to present clock pulse generator, first counter, delay element, first register, first AND element, adder, additionally inserted are two keys, two analog-digital converters, second register and operative memory block for estimation results, to realize second control stage additionally to first and second comparison block, indication block, inserted are breakdowns signs memory block, breakdown counters and commutator, and for controlling control stages to present launch element, first counter, second AND element, key element is additionally inserted.

EFFECT: higher speed of operation.
