HIGH-PRECISION VARIABLE FREQUENCY OSCILLATOR, HIGH-ACCURACY OSCILLATOR, AND SYNCHRONOUS OSCILLATOR

摘要

PURPOSE:To obtain the high-precision variable the frequency oscillator which is simple in its configuration and is capable of executing highly precise frequency control. CONSTITUTION:Bias voltage V generated by a variable voltage source 13 is controlled by an external control signal, and the bias voltage V and a frequency discrimination signal are summed by an addition circuit 14. At that time, the change portion (relative value) of the output frequency of an atomic oscillator becomes (KvRb0-1 V. Here, K is frequency discrimination sensitivity. Accordingly, the change of the output frequency to the bias voltage V becomes linear.
