The utility model relates to a railway signal device, in particular to a pulse receiver. The pulse receiver comprises a signal input circuit, a frequency selecting circuit, an analog to digital (AD) switching circuit, a digital filtering circuit, a digital signal process (DSP) circuit, a judging module, a safety and gate circuit and a power circuit. The signal input circuit, the AD switching circuit, the digital filtering circuit, the DSP circuit and the judging module are in electric connection successively. A first output terminal of the judging module and the input terminal of the safety and gate circuit are in electric connection. The output terminal of the safety and gate circuit is taken as the first route of output and a second output terminal of the judging module is taken as the second route of output. The frequency selecting circuit and the DSP circuit are in electric connection. In the state of adjustment, when interference signals invade, the pulse receiver can lead track relays to be stable and r
