Your assignment is to design a digital clock that displays seconds, minutes, and hours, in standard, i.e. non-military, time. The input to your circuit will be a clock signal with a one-second cycle time (one rising edge every second), and the output will be six seven-segment displays. positive edge-triggered J-K flip-flops, and any circuits you have previously designed, or have been designed in class. You should design any new circuits needed, showing all your work and circuit diagrams, and clearly show how the counters are cascaded together. Your final solution should be a block diagran where the counters and decoders appear as boxes with all inputs, outputs, and connections clearly labelled. Note that there is some subtlety involved in th hours display. In particular, the count sequence must be correct, and a zero leading digit should not be displayed for the hours. You must show that your circuit will not cycle through unused states indefinitely. Be sure that the clock inputs to all flip-flops are clearly specified and indicated. You may use
