What does AAU stand for? Consider the following properties of a particular network theorem: 1. The theorem is not concerned with type of elements. 2. The theorem is only based on the two Kirchhoff's laws. 3. The reference directions of the branch voltages and currents are arbitrary except that they have to satisfy Kirchhoff's laws. Which one of the following theorems has the above characteristics? Current stability of a CC amplifier can be increased by The state variable representation of a system is given as \[\begin{array}{l} \mathop x\limits^ \cdot = \left[ {\begin{array}{*{20}{c}} 0&1\\ 0&{ - 1} \end{array}} \right]x,\,x\left( 0 \right) = \left[ \begin{array}{l} 1\\ 0 \end{array} \right]\\ y = \left[ {0\,\,1} \right]x \end{array}\] The response y(t) is Consider a multiplexer with X and Y as data inputs and Z as control input. Z = 0 selects input X and Z = 1 selects input Y. What are the connections required to realize the 2-variable Boolean function f = T + R, without using any additional hardware?
