Waveforms and Their Types

Study Notes

A waveform is a visual representation of a wave's shape and pattern over time or space.
It is a graph that displays the amplitude (y-axis) versus time (x-axis) or distance (x-axis).

Sine Waveform: A continuous, smooth, and curved waveform with a single frequency.
Square Waveform: A waveform with a sudden transition between two amplitude levels, resulting in a square shape.
Triangular Waveform: A waveform with a gradual increase and decrease in amplitude, forming a triangular shape.
Sawtooth Waveform: A waveform with a gradual increase in amplitude, followed by a sudden drop, resulting in a sawtooth shape.
Complex Waveform: A waveform composed of multiple frequencies and amplitudes, resulting in a complex and irregular pattern.

Amplitude: The maximum displacement or intensity of the waveform.
Frequency: The number of oscillations or cycles per second.
Wavelength: The distance between two consecutive points on the waveform that are in phase.
Period: The time taken for one complete oscillation or cycle.
Phase: The relative position of a waveform in its cycle.

Audio Analysis: Waveforms are used to visualize and analyze audio signals in music and speech processing.
Signal Processing: Waveforms are used to analyze and filter signals in various fields, such as communication systems and biomedical engineering.
Medical Imaging: Waveforms are used to analyze and visualize medical signals, such as ECG and EEG.
