Logic circuit

Consider the attached circuit. Assume that the three states are initially at the 0 logic level. Which of the given tables is true for the function performed by this circuit? The leftmost column represents the clock pulses. initially there is no pulse (1st row). As the first clock pulse arrives the resulting change of state is shown on the second row and so on.

A saturated npn transistor has a base to emitter applied voltage of 0.6V. The collector to emitter voltage is 0.2V. The collector current is 12mA. The beta value of the transistor is 30. What is the emitter current?

circuit analysis

Refer to the following circuit. Assume that the switch has been open for a long time, and that it closes at time=0sec. The switch remains closed therafter. Solve for Vx(t) and ix(t) as shown on the circuit diagram.
