As a sinusoidal signal is clipped the waveform approaches a square wave.
Transfer function is the relationship between output and input of a circuit. In the clipping circuit, the general transfer function is such that the transfer curve Av is less than 1 for passive limiter and greater than 0 to limit the maximum and minimum voltage value.
A: SIGNAL could overshoot a value which can damage the input or output therefore a diode is used to clip these signals to a safe level
The three waveforms in the trigger circuit of an oscilloscope are the sine wave, square wave and saw tooth wave.

Triangular wave
A rectifier circuit produces a unidirectional wave form.
clipper circuit is used to remove some part of wave form(positive part,negative part or peak)... clamper circuit is used to shift the wave form (up or down) ....
applications of clipper circuit
something to drop the excess voltage across while clipping.
Friend, This is pretty difficult to explain without maths and a diagram, but I will give it a try. If you have seen a sinusoidal wave, which is like the "electrical component" of an electromagnetic wave. (Well, just imagine a wave), from zero it goes up to a certain level (called a crest) and to zero level and goes to a negative level (called trough). In some applications, like voltage regulators, you do not need the wave to the highest level. So what you do is to chop off the topmost part of the wave so that it meets your needs. The level of the clipping (chopping of the topmost part) is determined by the circuit. If you chop off the negative extreme (trough), it is called negative clipping.
Clipping circuit is a wave-shaping circuit, and is used to either remove or clip a portion of the applied wave in order to control the shape of the output waveform. One of the most basic clipping circuit is the half-wave rectifier. A half-wave rectifier clips either the negative half cycle or the positive half cycle of an alternating waveform, and allows to pass only one half cycle. Such a circuit has great applications in radars, digital computers and other electronic systems for removing unwanted portions of the input signal voltages above or below a specified level. Another application is in radio-receivers for communication circuits where noise pulses that rise well above the signal amplitude are clipped down to the desired level. Clipping circuits are also referred to as voltage limiters, amplitude selectors, or slicers.
A thyristor is a semiconductor device which acts as a switch.

In what context? Assuming signal transmission, the main disadvantage of a clipping circuit is that the data transmitted at values outside the circuit's range will be "clipped" (for example, if the clipping value is 20V, and the signal is 23V, the output will be 20V). This is esp. visible with audio circuits, and with electron tube circuits in general. The main advantage, at any rate, would be that a clipping circuit would serve as, say, an overvoltage protection for sensitive devices. But that is a bit of guessing on my part. If the circuit (or circuits) are to be designed properly, I would say that a bridging circuit should be built instead - a circuit that would "shake hands" between two other circuits, bringing their respective levels to a level common for both, or by translating between the two.
