Audio Oscillators December 7, 2017 Engineeering Projects RC oscillators are principally used for generating audio frequencies. Two popularly used RC oscillators are (i) RC phase shift oscillator using either BJT or FET and (ii) Wien Bridge oscillator. Another popularly used audio oscillator is the Beat Frequency Oscillator (BFO).

Audio Oscillator with Frequency Counter. This project is not completely new. In fact, the oscillator is made from the same schematic as in one of my previous projects and only the frequency counter is made with different schematic. After I finished the oscillator, I made some minor changes in the square signal part of the schematic.

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 ...

As with an audio millivoltmeter ( Project 16) which is a natural companion for an oscillator, it is not possible to use a standard opamp for the oscillator because of the frequency response needed. A variation of a discrete opamp is used for this design, using common bipolar transistors.
