摘要：
A function generating circuit for producing a control signal for an oscillating circuit that vibrates a crystal unit includes a temperature detecting circuit to detect an ambient temperature, and a Bezier-curve generating circuit to produce a Bezier curve as the control signal in response to the ambient temperature detected by the temperature detecting circuit.
