Unformatted text preview: controller represent a 3-bit number, which indicates what is to be displayed. There are nine outputs, A - I, one for each of the dots. A dot will light when given a 1, and is unlit when given a 0. Use a decoder and OR gates. Problem 6: Implement a visual device which counts down for (a) 6-to-0 using the die (Problem 5) and (b) 9-to-0 using the 7-segment code (Problem 1). One input is given, Y. The device should count down when the 1-bit input Y = 1, and does not count when Y = 0. Use only D flip-flops and k-input multiplexers. (You can assume that you have the devices from Problem 1 and 5 available, specified using your design)....
