INTRODUCTION - Talking Electronics

See Talking Electronics WEBSITE email Colin Mitchell: is the second half of our Transistor Circuits e-book. It contains a further 100 circuits, with many of them containing one or more Integrated Circuits (ICs).It's amazing what you can do with transistors but when Integrated Circuits came along, the whole field of Electronics exploded. IC's can handle both analogue as well as digital signals but before their arrival, nearly all circuits were analogue or very simple " digital " switching 's explain what we mean. The word analogue is a waveform or signal that is changing (increasing and decreasing) at a constant or non constant rate. Examples are voice, music, tones, sounds and frequencies.

Then digital came along. Digital is similar to a switch turning something on and off. The advantage of digital is two-fold. Firstly it is a very reliable and accurate way to send a signal.
