Clipper and clamper circuits lab manual

Clampers Clampers are diode circuits that can be used to add a DC level to an AC signal. They are also known as DC restorers. Like clippers, clampers use diodes and resistors; Unlike clippers, clampers use capacitors (for charging to appropriate DC level). Why add DC level? • If offset is needed for a particular operation. A clamping circuit is used to “clamp” a signal to a fixed DC level. This is also known as “DC restoration.” This term dates back to the first television receivers which needed to restore a transmitted signal to a reference value to set the black level. A simple clamping circuit is . The output waveforms of Figure (1) summarize the circuit action. The biased clipper removes all signals above the (+V) level. 2. Clamping Circuits: A clamper does is adding a DC component to the signal. In Figure (2) the input signal is a sinewave, the clamper pushes the signal upward, so that the negative peaks fall on the 0V level.

To realise different clipping and clamping circuits and observe the waveforms. THEORY Clipping Circuits Clipping circuits are nonlinear wave shaping circuits. A clipping circuit is useful to cut off the positive or negative portions of an input waveform. Clipping circuits are also known as voltage limiters or slicers. Positive clipper. A clamping circuit is used to “clamp” a signal to a fixed DC level. This is also known as “DC restoration.” This term dates back to the first television receivers which needed to restore a transmitted signal to a reference value to set the black level. A simple clamping circuit is shown below in fig. 7. 2 DIODE CLIPPER AND CLAMPER CIRCUITS. Aim: To learn about clipping and clamping of signals using diodes and passive elements. Pre-lab work: 1. Read the theory of these circuits. One possible source is Microelectronics, by Millman and Grabel. 2. This Laboratory sheet gives only a brief exposition of the theory. 3.
