What is the primary function of an oscillator in the context of electrical circuits?

1. Convert A.C. to D.C.

2. Alter voltage

3. Generate high frequency signals

4. Store charge

The correct answer is: Generate high frequency signals

The primary function of an oscillator in electrical circuits is to generate high-frequency signals. Oscillators are electronic circuits that produce a repetitive waveform, typically in the form of sine, square, or triangle waves. These waveforms are crucial in various applications, such as in radio frequency transmission, clock generation for digital devices, and sound synthesis in audio applications. By producing oscillating signals, oscillators serve as the backbone for timing and signal generation in numerous electronic devices, allowing them to operate at specific frequencies necessary for their functions. In essence, they establish a consistent and stable reference frequency that can be used for synchronization and modulation. Other options presented are focused on different electrical functions. Converting AC to DC pertains to rectifiers, while altering voltage is associated with transformers or voltage regulators. Storing charge relates to capacitors or batteries. Each of these plays a distinct role in electrical circuits but does not encompass the fundamental purpose of oscillators.
