A phase lead network has the transfer function G\left( s \right) = \frac{{1 + 0.2s}}{{1 + 0.05s}}. The angular frequency at which the maximum phase shift for the network occurs is
Consider the Signal x[n] = sin (2πn) u[n], where u\left[ n \right] = \left\{ {\begin{array}{*{20}{c}} {1\;\;n = 0,\;1,\;2,\;3,\; \ldots }
\\ {0\;\;\;otherwise} \end{array}} \right.
The period of the signal x[n] is
