Claims

[Scope of utility model registration request]

In a vehicle-mounted receiver that performs a predetermined operation based on the detection output of the level of the received signal, the ignition noise reception operation is performed in synchronization with the output of the ignition circuit of the engine installed in the vehicle. A circuit for forming a pulse-like noise removal signal having a time width such that the influence is substantially negligible is provided, and the signal is mixed into the received signal based on the noise removal signal from the noise removal signal forming circuit. An on-vehicle receiver characterized by removing ignition noise components.
