Similarly, it is possible to clamp the input wave form positively at 10v by reversing the battery connections as shown in fig 3b. A clamper circuit can be defined as the circuit that consists of a diode, a resistor and a capacitor that shifts the waveform to a desired dc level without changing the actual appearance of the applied signal. A clipper is a device which limits, remove or prevents some portion of the wave form input signal voltage above or below a certain level in other words the circuit which limits positive or negative amplitude,or both is called chipping circuit. Their low forward voltage drop and fast switching characteristics make them superior for most signal clipper and clamper circuits.

Working of clipper circuit the clipper circuit can be designed by utilizing both the linear and nonlinear elements such as resistors, diodes or transistors. As these circuits are used only for clipping input waveform as per the requirement and for transmitting the waveform, they do not contain any energy storing element like a capacitor. A clipper does not distort the remaining part of the applied waveform. Clippers can be broadly classified into two basic types of circuits. Wave shaping circuits are the electronic circuits, which produce the desired shape at the output from the applied input wave form. A clipper circuit that removes the negative half cycle is called negative clipper. I have learned to solve clipper circuit with and with out battery in parallel to the output node.
