Q. Explain the application of clippers.
There are numerous clipper applications. In general clippers are used to perform one of the following two functions:
· Changing the shape of the waveform .
· Circuit transient protection.
Changing the shape of waveform.- Clippers can alter the shape of a waveform..For example a clipper can be used to convert a sine wave into a rectangular wave,square wave etc.They can limit either the negative or positive alteration or both alternations of an a.c. voltage .
Circuit Transient protection.-Transients can cause considerable damage to many types of circuits e.g a digital circuit .In that case a clipper diode can be used to prevent the transient from reaching that circuit.
