る信号処理装置。″It is attached to the fishing net towed behind the ship, and uses ultrasonic waves to detect a received signal containing information on schools of fish, fishing gear, etc., and after frequency-modulating this received signal and amplifying the power, transmits it to a transmitter. In a fishing net monitoring device that is configured to transmit data underwater toward a ship via , a frequency divider circuit that sends out a signal divided into two frequencies with the relationship Q2>Q3, and the output signal of the frequency divider circuit are applied, and when reading, the Q2 signal operates the storage element, and when writing A signal processing device in a fishing net monitoring device configured to be connected to a memory circuit equipped with a write/read controller that sometimes controls the memory element to operate with a Q3 signal. ″
