Abstract
THE PERFORMANCE of a servomechanism is often improved by modifying the data signal with compensation networks. For a-c servomechanisms, a-c (sometimes termed carrier-frequency) compensation networks are employed which modify only the modulation, because the data appear as modulation on a carrier. To determine the effect on the data signal of such an a-c compensation network, let us examine the action of the 2-phase motor as a demodulator.
