ABSTRACT:
Apparatus for setting up the tuning frequency of a phase locked loop is provided which utilises the voltage controlled oscillator of the phase locked loop itself. The apparatus includes signal translation circuitry which can provide a control voltage to the VCO of the phase locked loop dependent on a tuning voltage which is alterable in response to the frequency of the signal output by the VCO.
