Found in an American publication from 1968, this circuit aims to keep the torque of a DC motor constant. The power transistor depends on the motor.
This configuration was found in a 1976 publication. The outputs of the logic circuits are applied to...
With this circuit it is possible to measure frequencies up to about 500 kHz using a common...
The very high-input impedance of the CMOS gate allows this kind of device to be used as a...
