In a crowded curriculum, when time is short, the focus is on what a square root means, in what circumstances one might want to evaluate one, how they are related to squares, and how to use and interpret them.
Moreover, the rate of decay of closed forms is t and t2 and both functions in time domain are non-causal which require a time delay of significant length to be able to become physically realizable.Figure 2 (a) and (b) shows the variation of raised cosine and its square root signal pulses for different values of excess bandwidth parameter, AY and the variation of their both functions realizable.
Then multiplying by 0.5(A + x) leads to a lower bound approximately equal to 2u for the argument of the square root, since A [is greater than][approximately equals] 1.

Now, the square root part of the first of these solutions can only be an integer if q is even--because of the remainders obtained when odd or even squares are divided by four (1 and 0 respectively)--and the square root part of the second solution cannot be an integer unless q is odd.
