So like a spring mass motion, it must be stopped abruptly then allowed to float for echoes or external waves into a high impedance amplifier. | |

| Mar 14, 2021 at 8:36 | comment | added | Landon | So you short-circuit the ultrasonic transducer to discharge it because it charged up like a capacitor during the transmitting stage? | |
| Mar 14, 2021 at 8:35 | comment | added | Landon | Ringing as in transmission line ringing? Is this because although everything is impedance matched in the circuit, there is an acoustic impedance mismatch between the transducer element and the water? | |
