R-C OR R-L PARALLEL CIRCUIT SEPARATING TESTING APPARATUS USING MULTIPLIER

摘要

The device comprises a multiplier (7) for multiplying sinusoidal voltage (s) of a sinusoidal generator (1) by a output voltage (r) of a current/voltage conversion amplifying unit (3), an measuring object (2), a RMS value detecter (4), an A/D converter (5), a personal computer (6), and a lowpass filter (8) for removing the highpass component from the output of the multiplier (7) to send the output to the A/D converter (5).
