Abstract
A transmission circuit transmits an ultrasonic signal from an ultrasonic vibrator by driving a terminal voltage of the ultrasonic vibrator using a first pulse signal and then further driving the terminal voltage using a second pulse signal having an opposite phase to the first pulse signal. At least one of a pulse number of the second pulse signal and a pulse level of the terminal voltage is arbitrarily set.
