摘要：
The circuit presented uses a single-gang potentiometer to control the frequency of oscillation. This is achieved by making the components in the two arms of the bridge in a large ratio to one another, in such a way that the attentuation of the network alters only slightly as one of the resistors is varied. Such a change of attenuation can then be compensated for by the usual thermistor in the negative feedback path of the maintaining amplifier.
