Reference: Instrumentation and Simulation for Ultrasonic Measurements Instrumentation for ultrasonic velocity and attenuation measurements in liquids and solids is described. 5 MHz pulse generator is assembled using CMOS integrated circuits (4011, 7414, 74121, and 4010), having pulse width 2 microseconds to 60 microseconds. The wideband receiver is developed using Wideband Low Distortion, High Gain Operational Amplifier (OPA 643). The gain and bandwidth of the receiver are 50 dB and 10 MHz respectively. Transit time measurement has been taken on personal computer using analog to digital converter card. The system is found suitable, accurate and versatile for ultrasonic velocity and attenuation measurements.
