1. A circuit for causing an element to provide a response which is linearly proportional to an input signal comprising input signal means for providing an input signal, a microprocessor coupled to said input signal means for receiving said input signal and producing a first output signal which is dependent on the characteristics of a transistor oscillator to which it is coupled for the purpose of causing said transistor oscillator to provide an output other than which it would produce if said input signal means were coupled directly to said transistor oscillator, a transistor oscillator coupled to said microprocessor for receiving said first output signal and producing a second output signal which is linearly proportional to said input signal, and an element coupled to said transistor oscillator for receiving said second output signal and providing a response which is linearly proportional to said input signal.
