    摘要: Circuit arrangement for stabilising the speed of a d.c. motor which is controlled via a control amplifier, and drives a tacho-meter which is connected between the bases of a "long-tailed pair," a tuned circuit being included between the collectors which is tuned to the tacho frequency and which attenuates the other frequencies, the voltage across the tuned circuit being applied to the control amplifier via a charge pump.
