This triangle wave generator is made with a trigger Schmitt that converts a triangle wave into a rectangular one used to charge and discharge a capacitor through current sources. The positive current ...

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables, and other ...

A description of a four-phase RC oscillator of a sinusoidal and rectangular shape is given. A triangular-shaped signal is obtained by the counterphase addition of half-waves of sinusoidal signals ...

Function generator based on the AD9833 DDS chip and CH32V003F4P6 MCU. Outputs sine, triangle, and square waves with frequencies up to ~1 MHz. Amplitude up to 3.7 V for sine and triangle, 5 V for ...
