| Although there are a number of ICs available that convert frequency to voltage, this can also be done with discrete components as shown...
| From time to time one comes across appliances in second-hand goods stores that were designed for operation from a 110 V a.c. (50/60 Hz)...
| Although a 9.5-24 V direct voltage can be brought down to 5 V easily by a standard regulator, the converter described here has the advant...
| The power supply for this analogue circuit that affords delays of 330 seconds is taken directly from the mains. The direct voltage at the...
| A type 555 timer and some passive components can provide a small converter to provide a negative output of 12 V at a few milliamperes.
| Many function generators are based on a rectangular waveform generator consisting of a Schmitt trigger and integrator. The triangular sig...
| There are many ways of designing an analogue-to-digital converter: the present design is aimed particularly at a high speed. The speed is...
| Most frequency measurements are carried out by means of a digital frequency meter or else on an oscilloscope. However both these instruments...
| The well-known TTL IC type 74 I 21 is a monostable multivibrator that can be set to give an output pulse with a duration...
