Abstract
A circuit device includes a synchronization detection circuit which performs synchronization detection of a physical quantity signal of an input signal and outputs the physical quantity signal, and a filter unit. The synchronization detection circuit includes first and second detection circuits, and the filter unit includes first and second filters. In a first mode, the physical quantity signal from the first detection circuit is input to the first filter, and the undesired signal from the second detection circuit is input to the second filter. In a second mode, the physical quantity signal from the first detection circuit is input to the first filter and the second filter.
