Simple Triangle Wave Generator Circuit using IC LM358
In this article, we will learn how a triangle wave rises and falls repeatedly. Smaller waves, called harmonics, create this special wave and its shape looks like a triangle because these smaller waves fit together like bricks. Harmonics in triangle wave get weak fast and is not strong like square wave, so triangle wave is […]
