In the circuit shown below, shown S is closed at t = 0. The time constant of the circuit and initial value of current i(t) are Which of the following unit protects the memory? For accurate clock period in 8085 it is preferable to use Two systems are defined by their state veritable equation in time domain dx(t)/dt = Ax(t) + Bu(t) as follows. If the gain equation in this are as given below, which of the following choices is correct? \[\begin{array}{l} {\rm{A}} = \left[ {\begin{array}{*{20}{c}} { - 2}&1\\ 0&{ - 1} \end{array}} \right],\,{\rm{B}} = \left[ \begin{array}{l} 1\\ 0 \end{array} \right]{\rm{. }}{\rm{. }}{\rm{. }}{\rm{.
