1-12-1992 | The simplest solar-cell supply system consists of three parts: a diode, a solar-cell panel, and a rechargeable battery. The diode prevent...

1-12-1992 | Although there are a number of ICs available that convert frequency to voltage, this can also be done with discrete components as shown...

1-12-1992 | Timer chip ICM7250 from Maxim enables a very simple timer to be designed. The IC has eight programmable inputs for connectlng to, say, tw...

1-12-1992 | The governor described in this article is intended primarily for small 12 V motors that draw a current of not more than 2 A. Many governo...

1-12-1992 | 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-...

1-12-1992 | Most debounce circuits shorten or lengthen the time a switch is pressed to obviate interference pulses caused by switch bounce. The pres...

1-12-1992 | The charger makes cunning use of the properties of a Type 555 timer. The tnternal window comparator of the lC is set to 4.7 V by zener dio...

1-12-1992 | One advantage bipolar opamps have over FET types is that their input noise level is appreciably lower. However, when abipolar opamp is us...

1-12-1992 | Control elements in electronics often use a small current to control a large one. In fact, this is such a common situation that there is...

1-10-1992 | Some methods used in electronics are based on models that cannot, in fact, be the case. For example, currents flow continuously and yet co...
