This document summarizes an experiment on diode clipping and clamping circuits. It includes the objectives, equipment used, circuit diagrams of clipping and clamping circuits tested, and results from those circuits. Key findings are: 1) clipping circuits cut off portions of the input signal above or below certain voltage thresholds, while clamping circuits shift the entire signal up or down by a fixed amount. 2) In a clipping circuit, diodes allow the output to follow the input until a threshold is reached, then clamp the output at that level. 3) A clamping circuit uses a capacitor, diode, and resistor to shift the entire signal down by twice the peak input voltage.
