    The proper name for this circuit is “ astable multivibrator ”. It is a simple, free-running oscillator circuit timed by the sizes of the resistors, capacitors, and power supply voltage. Unfortunately, its output waveform is very distorted, neither sine wave nor square. For the simple purpose of making an audio tone, however, distortion ...

    An introduction to Audio Oscillators also known as RC Oscillators. So far, we have considered the oscillators which use L-C tuned circuit that causes a phase shift of 180° due to inductive or capacitive coupling in addition to a 180° phase shift produced by the transistor itself. The oscillators employing L-C elements, called the L-C oscillators, are very popular for …

    The “Code Practice Oscillator” is a simple to build audio oscillator designed to be used as a morse code practice oscillator. The CPO is built on a double sided circuit board and mounted to a small wooden breadboard. Unlike many currently available CPO’s using a sawtooth oscillator, the “CPO” uses a more pleasant sounding sine wave
