Research output: Chapter in Book/Report/Conference proceedingChapter


The output signal of the device described is proportional to the relative difference between the rms values of two single-frequency voltages of from 0.003 to 3 V in the frequency range of 100 Hz to 2 MHz with a resolution of not lower than 0.001%. The device operates by comparison with a standard measure; therefore, it can be used in flaw detection, mensuration, and metrology as well as in physics experiments in which the standard and measured quantities can be represented by ac voltages.
