1. A voltage controlled oscillator comprising:

  • (a) an oscillating circuit having two control inputs and means for outputting an oscillator output signal, said oscillating circuit being adapted togenerate said oscillator output signal at a frequency dependent on a difference between voltages applied to said control inputs; and

    (b) an input control circuit comprising first input means for providing a first control input signal of a first polarity to one of said two control inputs and second input means for providing a second control input signal of a second polarity opposite to said first polarity to the other one of said two control inputs.
