Calibrated encoder multiplier |
摘要 |
A device for receiving first and second analog signals consisting of two sinusoidal signals shifted in phase from an encoder and outputting digital pulses corresponding to the approximate number of equal steps the system of which the encoder is a part has advanced or retreated comprising flash memory storing a table relating total value counts to the precise value as previously determined by calibration and that adds or subtracts counts to or from a difference register so that the count in the difference register corresponds to the calibrated value moved by the system.
