    • The control voltage for a VCO (voltage controlled oscillator) is produced in a phase locked loop which in turn is controlled by a computer (40) including an integrated analog circuit (42). First the oscillator control voltage is set to a predetermined value. Then, voltage varying steps are performed. For performing these steps, the circuit includes a main frequency divider and a reference frequency divider both functioning as counters. The beginnings of the counting of each divider are synchronized with each other. The oscillator control voltage is increased by a predetermined voltage difference or increment when the reference divider completes its counting period prior to the main divider completing its counting. The oscillator control voltage is decreased by a predetermined voltage difference or decrement when the main divider finishes its counting period prior to the reference divider finishing its count.
    • VCO(压控振荡器)的控制电压在锁相环中产生,锁相环又由包括集成模拟电路(42)的计算机(40)控制。 首先将振荡器控制电压设定为预定值。 然后,执行电压变化步骤。 为了执行这些步骤,该电路包括主分频器和用作计数器的参考分频器。 每个分频器的计数开始相互同步。 当主分压器完成其计数之前,当参考分压器完成其计数周期时,振荡器控制电压增加预定的电压差或增量。 当主分压器在参考分频器完成其计数之前完成其计数周期时,振荡器控制电压减小预定的电压差或减小。
