How diode acts as clipper and clamber?

A diode acts as a clipper by preventing a portion of the input signal from passing through, effectively "clipping" the waveform at a certain voltage level. This is achieved by connecting the diode in such a way that it conducts only when the input voltage exceeds a specific threshold, allowing only the desired portion of the signal to pass. Conversely, a diode acts as a clamper by shifting the entire waveform up or down without altering its shape, typically by adding a DC offset. In this configuration, the diode allows for the movement of the signal to a new reference level while maintaining the original signal's amplitude and frequency characteristics.
