Regulated Power Supplies,pment it is usually taken to mean those types supplied from the 240 V 50 Hz mains and providing a d.c. output. Furthermore, although two basic types exist, constant voltage and constant current, by far the most usual and hence the most important is that of the constant-voltage type, the basic purpos

Sinewave Oscillators and Pulse Generators, system invariably requires some sort of waveform to be generated as part of its function; examples of such waveforms are shown in figure 3.1. All these waveforms are capable of being produced by electronic circuits known as . and since the waveform is generated completely within the circuit itself

Digital Electronics,at a solution to a problem the process is one of a series of yes/no decisions taken in sequence to arrive at an overall result. Electronic circuits may be used to form a ‘model’ of a particular problem and by the use of simple ON/OFF circuits simulating the alternatives, the solutions to complex pro

A. Simpson C.Eng., M.I.E.R.E.omagneticians and to the first radio experiments. In 1902, in the very early days of radio, a high altitude conducting layer was suggested as a mechanism to allow for long distance propagation of radio signals travelling far around the curvature of the Earth. Theoretical efforts to explain this phen
