Question: 1 / 400

What device is utilized to produce high frequency signals?

Transformer

Rectifier

Oscillator

The device used to produce high frequency signals is indeed an oscillator. An oscillator generates periodic waveforms, which can include sine waves, square waves, or triangular waves, among others. These waveforms can be used in various applications such as radio transmission, clock generation, and signal processing. Oscillators can operate at different frequencies, including high frequencies, and are essential for creating signals that can be modulated or applied in electronic circuits for various purposes.

Transformers are primarily used to change voltage levels in AC circuits, not to generate signals. Rectifiers convert AC to DC power, without creating high-frequency signals. Amplifiers, on the other hand, are designed to increase the amplitude of signals rather than generate them. Therefore, the function of producing high frequency signals is specifically characteristic of oscillators.
