ABSTRACT:
An improved ultrasonic inspection system is provided which allows ultrasonic inspection to be performed using either of two ultrasonic frequencies and which also provides improved system sensitivity and dynamic range. In operation, the system produces two signals, one an amplified receive transducer signal and the other an attenuated receive transducer signal. Each signal is converted into a logarithmic representation. The two logarithmic representations are selectively provided to a read-only memory, which operates to output a signal corresponding to the receive transducer signal. Means are also provided which allows the system to use either of two ultrasonic frequencies.
