  • Apparatus and method for presenting a modulated output signal at an output locus
    Patent number: 7436263
    Abstract: An apparatus that presents an output signal that is modulated by input signal includes: (a) A signal source providing a signal at a reference frequency. (b) A frequency comparer coupled with the signal source and the output signal for comparing the extant output signal frequency with the reference frequency and generating an indicator representing the comparing. (c) Value storing units coupled with the frequency comparer to respond to an indicator and store a parameter associated with one of predetermined frequencies. (d) A selector coupled with the value storing units. (e) A signal controlled oscillator coupled with the selector. The selector responds to the input signal to couple a value storing unit with the oscillator for providing a parameter to the oscillator for effecting the modulation.
