driehoeksgolven

Driehoeksgolven, or triangular waves, are a type of periodic waveform characterized by its resemblance to a triangle. Unlike the smooth curves of a sine wave or the sharp transitions of a square wave, a triangular wave exhibits a gradual, linear increase and decrease in amplitude. The waveform rises at a constant rate to a peak, then falls at a constant rate to a trough, before repeating the cycle. This linear progression gives it a distinct "sawtooth" appearance, but with symmetry.

The mathematical representation of a triangular wave is often defined piecewise. For example, over one period, it might be represented as a function that increases linearly from a minimum to a maximum value, and then decreases linearly back to the minimum. The amplitude of a triangular wave is the maximum displacement from its zero or average value. The frequency determines how many cycles occur within a given time period.

Triangular waves have applications in various fields. In electronics, they are used in signal generation for testing and in the creation of certain types of audio synthesis. Their predictable linear slopes can be advantageous in analog-to-digital converters and in some control systems. The harmonic content of a triangular wave is different from that of a sine wave or square wave, consisting of odd harmonics whose amplitudes decrease with the square of the harmonic number. This makes them sonically distinct.
