Squarewave Generator Circuits
Squarewave generators are among the most widely used of all circuits used in modern electronics. They can be used for flashing LED indicators, for generating audio and alarm tones, or, if their leading and trailing edges are really sharp, for ‘clocking’ logic or counter/divider circuitry, etc. Such circuits can be designed to give symmetrical or non-symmetrical outputs, and can be of the free-running or the gated types; in the latter case, they can be designed to turn on with either logic-0 or logic-1 gate signals, and to give either a logic-0 or a logic-1 output when in the OFF mode. The designs can be based on a variety of semiconductor technologies, including the humble transistor, the op-amp, the 555-timer ...
