What is audio frequency oscillator? An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave or a triangle wave. An audio oscillator produces frequencies in the audio range, about 16 Hz to 20 kHz. What is the frequency of LC oscillations?

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 circuit will oscillate at a frequency of around 1 kHz with C at 100 nF and R at 470 k. A peak to peak output amplitude almost equal to the supply rail potential is acquired at the squarcwave output, but the triangular output amplitude is much lower, being something in the region of 100 mV peak to peak.

The phase shift oscillator of the figure above produces a sine wave output in the audio frequency range. Resistive feedback from the collector would be negative feedback due to 180° phasing (base to collector phase inversion). However, the three 60° RC phase shifters ( R1C1, R2C2, and R3C3) provide an additional 180° for a total of 360°.

This simple circuit is an audio-frequency oscillator, and has the following schematic diagram: After repairing a broken solder joint, the technician notices that the DPDT switch has lost its label. The purpose of this switch is to allow polarity to be reversed so as to test both PNP and NPN transistor types.
