An internally generated space/time modulated electric field interacts with a rotor which is made of a dielectric composite material. The rotor includes a peripheral sinusoidally shaped 3D pattern that serves the Fine channel, and a recessed sinusoidal pattern that serves the Coarse channel. The electric field is integrated over the full rotor area (hence “holistic”) and the resulting signal is processed and separated into Sine and Cosine output channels. Since a common channel processes both the Sine and Cosine outputs they are nearly matched and the decoded angle is stable over time and temperature.
