Claim 19:
20. The apparatus as recited in claim 15 wherein, to represent a first value of the first information and a first value of the second information the modulation circuit generates the modulated signal with a fixed voltage;
to represent the first value of the first information and a second value of the second information the modulation circuit generates the modulated signal with at least a first frequency;
to represent a second value of the first information and the first value of the second information, the modulation circuit generates the modulated signal with a second frequency; and
to represent the second value of the first information and the second value of the second information, the modulation circuit generates the modulated signal using frequency modulation to thereby generate the modulated signal to have a third frequency and to have a fourth frequency supplied in an envelope having a fifth frequency.
