What is a clipper circuit? In electronics, a clipper is a circuit designed to prevent a signal from exceeding a predetermined reference voltage level. A clipper circuit can remove certain portions of an arbitrary waveform near the positive or negative peaks or both. Clipping changes the shape of the waveform and alters its spectral components … Read more
What does voltage divider mean? Potential divider In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). Voltage division is the result of distributing the input voltage among the components of the divide A … Read more
