The Sigma Function Generator offers three main waveforms: sine, square, and triangle. These waveforms are essential for testing and analyzing electronic circuits, as they represent the most common types of signals encountered in real-world applications.

Sine Wave

The sine wave is a smooth and continuous waveform that represents an oscillating signal with a constant frequency and amplitude. It is widely used in audio applications, such as music synthesis and sound testing.

Square Wave

The square wave is a waveform that alternates between two voltage levels, typically high and low. It is commonly used in digital circuits, as it represents binary signals and can be easily generated and manipulated.

Triangle Wave

The triangle wave is a waveform that ramps up and down linearly between two voltage levels. It is often used in applications that require a smooth and continuous change in voltage, such as motor control and frequency modulation.
