A variable audio oscillator operates within a frequency range of 20 hertz to 20 kilohertz. The circuit utilizes an Intersil 8038 waveform generator, which is designed in a 14-pin dual in-line package (DIP).

The variable audio oscillator circuit is designed to generate audio signals across a wide frequency spectrum, making it suitable for various applications such as sound synthesis, tone generation, and audio testing. The Intersil 8038 is a precision waveform generator capable of producing sine, square, triangular, and sawtooth waveforms, making it versatile for different audio applications.

The configuration of the Intersil 8038 involves connecting external resistors and capacitors to set the desired frequency of oscillation. The frequency can be adjusted by varying these external components. Typically, a potentiometer may be included in the circuit to allow for smooth frequency modulation, providing an intuitive user interface for real-time adjustments.

The 14-pin DIP package facilitates easy integration into various electronic projects. Key pins of the 8038 include the output pin, which delivers the generated waveform, and the frequency control pins, which are crucial for setting the oscillator's frequency range. Additionally, the circuit may include bypass capacitors near the power supply pins to ensure stable operation by filtering out unwanted noise.

In practical applications, the output waveform can be fed into an amplifier or directly into a speaker, depending on the desired output level. The design of the variable audio oscillator can be tailored further by incorporating additional features such as modulation capabilities, which can enhance its functionality in more complex audio generation systems. Overall, this circuit serves as a fundamental building block for audio signal generation in both educational and professional electronic environments.Variable audio oscillator with a range of 20 hertz to 20 kilohertz.
