| The precision full-wave rectifier circuit shown in the diagram accepts a.c. inputs of up to ±3 V, yet operates from a single +5 V supply v...
| A current detector and a threshold switch are not sufficient when in comes to building an electronic fuse. Such a circuit would be trigger...
| The AD8037 is a rather special opamp because its positive and negative inputs have internal clamps. The clamp at the negative input is e...
| This circuit enables a model train to shuttle continuously between two tracks. When the train travels from left to right across the track in...
| The upgrade consists of just a diode, but, if the internal system clock is used, it gives an improvement of some 6 dB in the THD+N measured...
| The corrector has the task to always connect a load to a direct-voltage source with correct polarity. It thus functions in the same way as a...
| Electronic circuits that draw a current of more than a few milliamperes should preferably not be powered by a battery: most are, therefore,...
| The frequency of the standard Wien bridge oscilator presented is made variable by maktng one of the arms a mono potentiometer. The bridg...
| Although a fuse is primarily intended to melt when the current through it becomes too large, there are times when this should not happen...
