Claims

[Scope of utility model registration request]

a detection unit that detects a physical quantity and outputs a detection signal according to the physical quantity; a filter that has a capacitor connected to a feedback circuit of an operational amplifier so as to remove high frequency components included in the detection signal; a conversion section that performs predetermined signal conversion on an output signal; and a reference signal generator that generates a reference signal in a signal transmitter that outputs an electrical signal corresponding to the physical quantity from the conversion section. and a signal comparator that compares the detection signal and the reference signal, and a circuit switch that is driven by the output signal of the signal comparator and opens and closes the connection of the capacitor to the feedback circuit, A signal transmitter characterized in that when the signal is smaller than the reference signal, the circuit switch disconnects the capacitor from the feedback circuit.
