Abstract
A transducer system with a transducer and circuitry for applying a pulse train to excite the transducer. The circuitry for applying a pulse train 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.
Claims21
A transducer system, comprising:
- a transducer;
- and
- circuitry for applying a pulse train to excite the transducer, comprising circuitry for selecting 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, wherein 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.
A method of operating a transducer system, comprising:
- applying a pulse train to excite a first transducer by selecting 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;
- wherein 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;
- and
- wherein the transducer produces a transmitted signal in response to the pulse train;
- and producing a received signal in response to the transmitted signal.
