INTRODUCTION
This is the third part of our Circuits e-book series. It contains a further 100 circuits. This time we have concentrated on circuits containing one or more IC's. 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 circuits.
