The block diagram of a system with one input u and two outputs y₁ and y₂ is given below

A state space model of the above system in terms of the state vector $$\underline x $$ and the output vector $$\underline y = {\left[ {\matrix{ {{y_1}} & {{y_2}} \cr } } \right]^\tau }$$ is

The logic function implemented by the circuit below is (ground implies a logic "0"

When the output Y in the circuit below is ‘1’, it implies that data has

The output of a 3-stage Johnson (twisted-ring) counter is fed to a digital-to-analog (D/A) converter as shown in the figure below. Assume all the states of the counter to be unset initially. The waveform which represents the D/A converter output V_o is
