PROBLEM TO BE SOLVED: To provide a train controller capable of reducing noise contained in a reception signal with a simple configuration in an environment in which inverter noise is generated.SOLUTION: A train controller comprises: a ground device transmitting an amplitude modulation signal; and a train-mounted device extracting train control information from frequency information on a modulation wave of the received amplitude modulation signal and controlling a train. The train-mounted device includes: frequency analyzing means 13c for analyzing a frequency of the received amplitude modulation signal and obtaining a frequency domain signal; intensity adjusting means 13d subtracting a frequency component intensity other than a primary frequency component of the amplitude modulation signal and a carrier frequency component from the frequency domain signal; signal converting means 13e for converting the frequency domain signal from the intensity adjusting means 13d to a time domain signal; and frequency information detecting means for detecting frequency information on the modulation wave on the basis of the time domain signal from the signal converting means 13e. |
