The following work explains the development and implementation of a low-noise and low-interference sensor circuit for transmitting and receiving ultrasonic waves in gases. The pattern of the signal can be changed complete freely, so that frequency or amplitude modulation is possible. The measurement results of the analog circuits are evaluated and discussed.
