A pulse receiving circuit which receives a receiving signal from the outside includes: a template pulse generating circuit which generates a first pulse signal and a second pulse signal having phase different from that of the first pulse signal based on a pulse position timing signal; a first multiplying circuit which multiplies the receiving signal by the first pulse signal and outputs a first multiplication signal; a second multiplying circuit which multiplies the receiving signal by the second pulse signal and outputs a second multiplication signal; a first low band pass filtering circuit which extracts low frequency component from frequency components of the first multiplication signal and outputs a first low frequency signal; a second low band pass filtering circuit which extracts low frequency component from frequency components of the second multiplication signal and outputs a second low frequency signal; and an envelope detection circuit which performs envelope calculation by using the first low frequency signal and the second low frequency signal and outputs a detection signal.
