Abstract
An electric circuit includes: a reference signal generation circuit that generates a reference signal based on a first oscillation signal that is an oscillation signal of a first oscillation circuit that vibrates a first vibrator; and a counter circuit that counts a second oscillation signal that is an oscillation signal of a second oscillation circuit that vibrates a second vibrator based on the reference signal, and outputs a count signal, wherein the count signal is a change of the count value in the second oscillation signal.
