I have an ultrasonic transducer that I am driving in pulsed mode from a fai rly stiff opamp source. The result being that when V=GND after transmitti ng the pulse there is almost no trace of ringing on the transducers Tx circ uit as the opamp feedback suppresses it.
The question becomes whether the face of the transducer will still efficien tly reflect other ultrasound pulse impinging on it, or whether it acts as s ome kind of active damper?
