摘要：
A circuit for driving ultrasound transducers uses a sample-and-hold circuit to sample multiple sample periods of a transducer driving waveform, and uses the samples to modify drive parameters. Use of multiple sample periods enables independent measurement and adjustment of different portions of the transducer driving waveform to ensure mirror symmetry.
