<p><P>PROBLEM TO BE SOLVED: To provide a pulse receiver capable of realizing the suppression of malfunction due to an interfering signal, quick synchronous recatching, stable synchronizing hold, and low error demodulation. <P>SOLUTION: The band limit and pulse width of a communication pulse signal received by a receiving signal 101 are changed so that an interfering wave signal 112 is suppressed by a filter 102 and the communication pulse signal is suited to demodulation in a demodulation circuit 103, and an output pass pulse signal is inputted to the demodulation circuit 103. In the demodulation circuit 103, a pulse position is extracted by a detector 104 and inputted to a correlator 107, a signal for determining a receiving signal timing is also input from a clock source 105 to the correlator 107 to perform correlation processing, a correlation discriminator 108 discriminates an error of signal timing by a signal obtained as the result of correlation processing to adjust the delay time of a delay 106, and demodulation is started after making the timing of the receiving signal to coincide with the signal timing of a receiving side apparatus. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
