A periodic signal x(t) of period T 0 is given by $$x\left( t \right) = \left\{ {\matrix{ {1,} & {\left| t \right| < {T_1}} \cr {0,} & {{T_1} < \left| t \right| < {{{T_0}} \over 2}} \cr } } \right.$$ the dc component of x(t) is For a signal x(t) the Fourier transform is X(f). Then the inverse Fourier transform of X(3f + 2) is given by Who introduced the paging system for the first time? Wagner earthing device is used to eliminate errors due to In the figure, the switch is thrown from position 1 to 2 at time t = 0. Just before the switch is thrown, the initial conditions are i L (0 - ) = 2 A, V C (0 - ) = 2 V. What is the current i(t) after switching action?
