How are Square and Triangle waveforms produced from Sinusoidal waveforms?

You could input your sine wave to a Schmitt trigger circuit to turn it into a rectangular wave. Integrating the rectangular wave you have a triangular wave.

Square and triangle waveforms are produced from sinusoidal waveforms using a process called waveform shaping. This involves manipulating the amplitude, frequency, and phase of the original sinusoidal waveform to create a square or triangle shape.

For a square waveform, the amplitude of the sinusoidal waveform is kept constant, but the frequency is doubled. This results in a waveform that alternates between two levels, resembling a square shape.

For a triangle waveform, the amplitude and frequency of the sinusoidal waveform are gradually increased and then decreased, creating a triangular shape. This can be achieved using various techniques such as filtering, modulation, or integrating and differentiating the original waveform.

Overall, the process of converting a sine wave to a square or triangle wave involves altering the original waveform to achieve the desired shape while maintaining its fundamental frequency. This is a fundamental technique used in signal processing and electronic circuit design.
