ABSTRACT:
A current controlled signal processor adjusts the characteristics of an output frequency of a current controlled type oscillation circuit in accordance with stored information. A control current is generated dependent on the stored information. The output frequency of a current controlled oscillator varies dependent on the control current. The stored information may be altered, thereby allowing for the altering of the output frequency of the current controlled oscillator without requiring replacement or addition of electronic elements. Also, the present invention makes it possible to assemble the current controlled signal processor circuits into one integrated chip.
