OBJECTIVE ▪ To be familiar with the clippers in an electric circuit and to be familiar with the clippers function in a MULTISIM/Labview Program. • To be familiar with two different types of the clippers. That is, positive clipper and negative clipper and to implement the positive clipper and negative clipper electric circuit in the MULTISIM Program./Lab view Software ▪ To be familiar with their wave forms as well. INTRODUCTION Clipper: a clipper is a circuit designed to prevent a signal from exceeding a predetermined reference voltage level. A clipper does not distort the remaining part of the applied waveform. Clipping circuits are used to select, for purposes of transmission, that part of a signal waveform which lies above or below the predetermined reference voltage level.Clipping circuits are also called slicers or amplitude selectors. Diode Clipper: A simple diode clipper can be made with a diode and a resistor. VIN VOUT This will remove either the positive, or the negative half of the waveform depending on the direction the diode is
connected. The simple circuit clips at zero voltage (or to be more precise, at the small forward voltage of the forward biased diode) but the clipping voltage can be set to any desired value with the addition of a reference voltage. The simplest circuit for the voltage reference is a resistor potential divider connected between the voltage rails. Positive Clipper: In a positive clipper, the positive half cycles of the input voltage will be removed the diode is kept in series with the load. During the positive half cycle of the input waveform, the diode 'D' is reverse biased, which maintains the output voltage at 0 Volts. This causes the positive half cycle to be clipped off.

Negative Clipper: The negative clipping circuit is almost the same as the positive clipping circuit, with only one difference. If the diodeis reconnected with reversed polarity, the circuits will become for a negative series clipper and negative shunt clipper respectively.the diode is considered to be the ideal one. AUTOM Negative Series Clipper and Negative Shurt Clipper -Vout- Sher In a practical diode, the breakdown voltage will exist (0.7 V for silicon and 0.3 V for Germanium). When this is taken into account, the output waveforms for positive and negative clippers will be of the shape shown in the figure below.
