1-07-2002 | In the form of the GP2D02, Sharp have produced a sensor which, with the aid of a microcontroller, can provide reasonably accurate measuremen...

1-07-2002 | This circuit does the exact opposite of what most of this type of changeover switches attempt to do. Usually a changeover switch is used wit...

1-07-2002 | Elsewhere in this collection of small circuits a 1-dB version of a third-order Chebyshev filter can be found. This 3-dB version is a bit ste...

1-07-2002 | A few years ago the charging of Nickel Cadmium cells was a fairly standard procedure. An AA sized NiCd cell used to have a capacity of 500 o...

1-07-2002 | Many CD-ROM drives have in addition to the analogue output also a digital S/PDIF output, in the form of two pins, typically next to the anal...

1-07-2002 | Interfacing your own equipment to GSM devices has been made difficult by the manufacturers because they don’t use standard connectors, very...

1-07-2002 | The general assumption is that white LEDs operate at a voltage of 3.6 V and a current of 20 mA, which is about right. Lithium Ion cells coin...

1-07-2002 | Those of you who are lucky enough to possess a DVD player and have watched a movie with lots of special effects, will certainly have noticed...

1-07-2002 | Display driver ICs are available in several standard implementations. This circuit makes use of a GAL 22V10 to drive two 7-segment displays...

1-07-2002 | In the ‘Audio Limiter (for DVD)’ circuit, the peak values of the audio signals are used to reduce the dynamic range of the sound. A possible...
