Waveform generation is the process of creating electrical signals that vary over time, often used in electronics and signal processing. These signals can take various shapes, such as sine waves, square waves, or triangular waves, and are essential for applications like audio synthesis, communication systems, and testing electronic devices. Devices called function generators or signal generators are commonly used to produce these waveforms. They allow engineers and technicians to manipulate frequency, amplitude, and phase, enabling precise control over the signals for various applications, including oscilloscope testing and modulation in communication systems.
