This trigger produces an output pulse when zeroing the input signal. The circuit is from a documentation from the 70s, presenting a hysteresis of 100 mV.
This circuit is from an old manual, but can be easily assembled as the integrated one is still...
The simple transistor test shown in the figure can be powered by a 9V battery. The test is for...
This regulator can use BD'136 as the main transistor and as a reference next to a BC548 zener. The...
