Oscillators are crucial to the working of all but the most mundane of electronic equipment. Like beating hearts, they send out the impulses that give life to radio transmitters and receivers, computers, frequency counters, calculators, timers, oscilloscopes, and signal generators of all kinds.For anyone who ever wanted to understand the mysteries of oscillators, this superb series is prepared with the electronics enthusiast and experimenter very much in mind and is intensely practical. Tried and tested circuits are fleshed out with component values, and their vices and virtues are exposed. The following offers a high-level overview of the topics covered in each article (note that more subjects are discussed than are referenced here).
