The open loop transfer function $$G(s)$$ of a unity feedback control system is given as, $$G\left( s \right) = {{k\left( {s + {2 \over 3}} \right)} \over {{s^2}\left( {s + 2} \right)}}.\,\,$$ From the root locus, it can be inferred that when $$k$$ tends to positive infinity

An open loop system represented by the transfer function $$G\left( s \right) = {{\left( {s - 1} \right)} \over {\left( {s + 2} \right)\left( {s + 3} \right)}}$$ is

The output $$Y$$ of the logic circuit given below is

A two-bit counter circuit is shown below

It the state $${Q_A}{Q_B}$$ of the counter at the clock time $${t_n}$$ is $$'10'$$ then the state $${Q_A}{Q_B}$$ of the counter at $${t_n} + 3$$ (after three clock cycles) will be
