design a light-bulb sequencing circuit. The circuit takes as an input a 16 hz clock, and it must illuminate eight light bulbs from right to left, one at a time, one per second, this process repeats forever.
It can be developed as a set of circuits...circuit 1: pulse generator, circuit 2: counter, circuit 3: bulb controller.
The pulse generator circuit accepts a 16 Hz pulse and converts the signal to a 1 Hz pulse, that is, a clock signal once every second. This signal is then used to drive a counter that controls how the lights are illuminated.
--Develop circuit 1 and circuit 2 as sequential circuits using the minimum number of D flip-flops and the minimum number of external gates.
--The job of circuit 2 is to set the values of the control lines appropriately to drive the combinational logic in circuit 3. Design the combinational logic circuit that controls the light bulb bank using the minimum number of 2 x 4 decoders and the minimum number of external gates.
Draw the detailed low level schematic of the overall system showing the flip-flops, decoders, as well the associated external circuitry.
