发明名称 Device for determining the rotational speed
摘要 A device for determining a rotation rate can be employed in conjunction with a rotation rate sensor which furnishes one or two output signals that among other things are a measure for the Coriolis acceleration and thus also for the rotation rate. The device includes an arrangement for signal processing, with which both digital subtraction of the output signals and an ensuing digital multiplication by a carrier signal shifted in a digital phase shifter are accomplished. The digital multiplication is followed by a digital/analog conversion and low-pass filtration, which in the final analysis furnishes an output signal (DR) that is equivalent to the rotation rate.
