In an ultrasonic diagnostic system, information as to the inside of the subject is indicated on the basis of a received signal which is obtained through receiving ultrasonic beams reflected within the subject. A difference signal is formed by subtracting a subtraction signal from the received signal, which subtraction signal is generated based on the received signal associated with a scanning line associated with the received signal or a scanning line different from the former scanning line. The difference signal is suitably amplified and analog-to-digital converted.
