signaaligeneraattore

A signaaligeneraattori, or signal generator, is an electronic device that produces repeating electronic signals in the form of a voltage or current. These signals are used to test, design, and repair electronic or acoustic equipment. Signal generators are essential tools in laboratories, research facilities, and repair shops.

Various types of signal generators exist, each suited for specific applications. Common waveform shapes produced include sine waves, square waves, triangular waves, and pulse waves. Some advanced generators can produce arbitrary waveforms, offering greater flexibility. The output signal is typically characterized by its frequency, amplitude, and waveform shape.

The primary function of a signal generator is to provide a known and controllable stimulus to a system under test. This allows engineers and technicians to measure the system's response and verify its performance. For example, a signal generator can be used to test the frequency response of an audio amplifier or the timing characteristics of a digital circuit.

In simpler terms, a signal generator acts like a controlled source of electrical "music" or "messages" that you can send into a device to see how it reacts. This helps in understanding if the device is working correctly or if it needs adjustments. The ability to precisely control the characteristics of the generated signal makes it an indispensable instrument in electronics.
