1-12-1994 | The Type UGN3140 Hall-sensor from Sprague enables a magnetic- field detector to be constructed that is conspicuous by its simplicity.

1-12-1994 | For measurements on alternating voltage, an active rectifier is normally needed to convert that voltage into a direct voltage which is a...

1-12-1994 | The circuit shown in here has been designed to protect (expensive) high-power resistors against overheating. Very high power resistors (...

1-12-1994 | The Type 7805 voltage regulator cannot handle input voltages higher than 35 V. If only voltages higher than 35 V are available, it is, o...

1-12-1994 | Modern central heating boilers have no pilot light but electronic ignition. Checking whether ignition has taken place can be carried out...

1-12-1994 | The domestic mains voltage, even at the best of times, does not have a clean wave form. For all sorts of reason, there are almost always...

1-12-1994 | The running lights are particularly suitable to demonstrate in an original manner how two data streams arrive alternately at the same po...

1-12-1994 | Normally, the standard probe supplied with an oscilloscope can be used only for measurements with respect to earth. This, occasionally...

1-12-1994 | When it comes to measuring alternating currents in a safe manner, crrent probes have a number of signtficant advantages over series res...

1-12-1994 | Normally, a comparator has inherent hysteresis, that is, when the Input voltage rises, the comparator will react only when the reference...
