| SWITCHABLE A.C. SUPPLY Many experiments in the electronics workshop require a.c. voltages simply by setting the alternating supply voltages...
| Halogen lamps are rightly popular because they give a good light and have an excellent efficiency. Unfortunately, they tend to be costly....
| If you ever need to derive a 5 V line from, say, a 15-25 V supply, National Semiconductors LM1575 and LM2575 are ideal. These switched 5-...
| Most debounce circuits shorten or lengthen the time a switch is pressed to obviate interference pulses caused by switch bounce. The pres...
| Any push-button switch can be used as a bounce-free, change-over switch with the aid of two D-type bistables contained in a 74HCT74 and...
| The logic relation 'exactly two of a,b,c, are true', or ((a,b,c,)), can perform all standard logic functions: for example, a = not b is (...
| The MAX743 DC-DC converter IC contains all the active circuitry needed to build smalI, dual-outpur power supplies. Relying on simple two-...
| Switching transistors are usually driven into saturation. which has an adverse effeet on the switching speed. This effect is eliminated,o...
| Binary-coded-decimal (thumb-wheel) switches are not only relatively expensive, but are also often not available to the wanted specificati...
