## What is Triangular Wave Generator

A triangular wave generator is an electronic circuit or device that produces a waveform characterized by linearly increasing and decreasing voltage levels, forming a triangular shape over time. It typically consists of an oscillator circuit that generates a continuous oscillation, and a voltage-controlled ramp generator that produces a voltage waveform with linearly increasing and decreasing slopes. The triangular waveform alternates between its peak positive and negative voltage levels at a fixed frequency, resulting in a waveform with symmetrically sloping edges. Triangular wave generators are used in electronic systems for applications such as waveform synthesis, modulation, frequency generation, and testing and calibration of electronic equipment.

## Working of Triangular Wave Generator

A triangular wave generator operates by using an oscillator circuit to produce a continuous oscillation, while a voltage-controlled ramp generator generates a voltage waveform with linearly increasing and decreasing slopes. The ramp generator’s output voltage increases linearly until it reaches a peak value, then decreases linearly until it reaches its minimum value, and the cycle repeats. This triangular waveform is produced at a fixed frequency determined by the oscillator circuit. The ramp generator’s output voltage alternates between its peak positive and negative levels, forming a triangular waveform with symmetrically sloping edges.
