Abstract: This paper introduces a multifunctional signal generator based on STM32 microcontroller for ground electric field detection applications. The signal generator can output a variety of ...

This project turns a single STM32 board into a 3-channel portable test instrument. It functions as both a 3-channel arbitrary waveform generator and a 3-channel oscilloscope, using the Arduino Serial ...

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 ...

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 article is part of the Ideas for Design Series: Vol. 3, No. 7. This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals ...
