Abstract: In circuitry for applying a pulse train to excite a transducer, the circuitry selects a first set having a first number of pulses at a first frequency and a second set of pulses having a second number of pulses at a second frequency differing from the first frequency. At least one pulse from the first set is located in the pulse train between one or more of the pulses at the second frequency.
