A radio wave monitoring apparatus includes a television receiver which is capable of receiving a radio wave in a television broadcast frequency band and generates reception quality information, and a wireless communication device which is capable of establishing communication in an area to be monitored and a wider area than the area to be monitored and transmits the reception quality information.

Radio wave monitoring apparatus

Disclosed herein is a detecting device including a coil electromagnetically coupled to the external, a resonant circuit that includes at least the coil, and a detecting section that superimposes a measurement signal for measuring the Q-factor of the resonant circuit on a power transmission signal transmitted to the coil in a contactless manner and removes the power transmission signal from an alternating-current signal obtained by superimposing the measurement signal on the power transmission signal. The detecting section measures the Q-factor by using the alternating-current signal from which the power transmission signal is removed.
