This circuit was obtained from a Philips documentation from 1968. The transistors can be replaced with equivalents, only with care so that the doubles are exchanged for matched pairs.
This control for motors up to 1 A was found in a Siliconix documentation using its own component....
This circuit uses one of two D-type flip-flops available on an integrated circuit 4013. The...
This simple circuit makes it possible to test visual fatigue by the ability to detect higher...
