Waveforms refer to the shape and form of a signal that varies over time. In the context of research, waveforms are often used to analyze and study various aspects of signals, such as electrical signals, sound waves, and seismic waves. Waveforms can provide important information about the frequency, amplitude, and phase of a signal, and are commonly used in fields such as communications, signal processing, and physics. Researchers often use techniques such as Fourier analysis to analyze and interpret waveforms in order to gain insights into the underlying phenomena being studied.
