Device for the detection of the state of rotation of a shaft, in particular for tape decks |
| 摘要 |
A rotatable capacitor of variable capacitance is utilized to produce modulation of a signal, and demodulation of the signal produces a signal usable for determining the state of rotation of a shaft used for rotating the capacitor.
