A triangular wave is a type of waveform that has a distinct triangular shape, characterized by a linear rise and fall. It alternates between a maximum and minimum value, creating a repeating pattern. The waveform is often used in electronics and signal processing due to its simple harmonic properties. Triangular waves can be generated using various methods, including oscillators and synthesizers. They are commonly found in applications such as audio synthesis and modulation, where their unique characteristics can produce interesting sound effects. The frequency and amplitude of a triangular wave can be easily adjusted, making it versatile for different uses.
