1. A current controlled signal processor, comprising:

  • a current controlled oscillator having an output frequency which changes with a control current;

    data storage means for storing and holding an electric signal;

    external information input means for inputting electric signal information to said data storage means;

    first current control means for controlling the current which flows into the current controlled oscillator dependent on an external control voltage and an output signal from the data storage means; and

    second current control means for controlling the current which flows through the current controlled oscillator dependent on the output signal from the data storage means.
