Estimating the term…
The use of power-efficient transmitters to establish acoustic wave energy having low undesirable harmonics is achieved by adjusting the transmitter output waveform to minimize the undesirable harmonics. In one embodiment both the timing and slope of the waveform edges are adjusted to produce the desired output waveform having little or no second harmonics. In the embodiment, output waveform timing adjustments on the order of fractions of the system clock interval are provided. This then allows for very fine control of a coarsely produced waveform. In one embodiment, the user can select the fine tuning to match the transmitter output signal to a particular load transducer.
A transmitter circuit for delivering acoustical energy to a transducer element;
The circuit of claim 6 wherein said portion of the transmitter output waveform comprises timing of a corner of the transmitter output waveform, wherein the timing of the transmitter output waveform corner is controlled by said timing control circuitry.
