Answer :

Necessity of Wave-shaping circuits:

1. To hold the waveform to a particular d.c level. 2. To generate one waveform from another. 3. To limit the voltage level of the waveform to some preset value and suppress all other voltage levels in excess of the preset level. 4. To cut off the positive and negative portions of the input waveform. 

(OR) 

In electronics application, it is often needed to alter the shape of waveform like cutting off positive or negative portion of wave, generation of one wave from other, holding wave at some dc level etc. To do this wave shaping circuits are needed.
