Abstract:
1. A template pulse generating circuit that generates a template pulse used for detection of a received pulse in pulse communication, comprising an output mode switching circuit that switches an output mode in accordance with a supplied control signal between a continuous output mode that continuously outputs the template pulses and an intermittent output mode that intermittently outputs the template pulses so that the template pulse is generated in either one of the continuous output mode and the intermittent output mode; and a variable mode pulse generating circuit that generates the template pulses one of continuously and intermittently in accordance with an oscillation mode switching signal supplied to a mode control signal input terminal, wherein the output mode switching circuit supplies the mode control signal input terminal of the variable mode pulse generating circuit with the oscillation mode switching signal, wherein the variable mode pulse generating circuit is configured including
