Basic digital signals are rectangular with sudden jumps to values of +1 and -1 according to the binary data. These sudden jumps create high sidelobes in frequency domain which makes co-existence of various wireless systems inefficient. Q2. Digital Modulation Techniques in Mobile Communications. Fahredd'n Sadikoglu 2 - Pulse shaping can be employed to remove spectral spreading.
The name comes from the shape of the spectral response, where the transition band of the filter follows a half-cycle of a raised cosine shape.

1st Nyquist Criterion for Zero ISI • In the first method, Nyquist achieves zero IS1 by choosing a pulse shape that has a non zero amplitude at its center (say t = 0) and zero amplitudes at t = (n = 1, 2, 3, . . .),bnT±) p ( , , , ), • We can write such a pulse as: bn • There exists one (and only one) pulse that meets Nyquist's 1st criterion and has a bandwidth Rb/2 Hz This pulse iscriterion and has a bandwidth Rb/2 Hz.
A pulse shaping filter is used in communication channels to manipulate a waveform or pulses to have the desired shape in the time domain. A pulse shaping filter can be a physical circuit, but normally it’s a mathematical function that is used as a signal processing algorithm.
