We found this relaxation oscillator in a 1967 General Electric documentation. The frequency is given by the capacitor. The obtained waveforms are shown.
This speed control for motors up to 500 mA was obtained in an old European documentation, but it...
This circuit cuts a rectangular signal, and a trapezoidal signal is obtained. The circuit is from...
This low frequency sinusoidal oscillator was obtained in documentation from the 1970s. Operational...
