Question:
Design a bit counter that can count either up or down up to on the rising edge of the clock.There are three input signals: a clock signal, a reset signal, and a signal to indicate whether thecounter should count up or count down. If the updown signal is high, the counter will count up ifthe input signal is low, the counter will count down. On reset, the count will return to zero.

c Draw the logic diagram for this counter.
d Draw the state diagram for this circuit
