Homework 5, Due 3-26-18 1. Design a 3-bit counter that counts in the sequence: 001, 011, 010, 110, 111, 101, 100, repeat. Use D flip-flops. Determine the next state of the counter if it initializes at 000 2. Design a 3-bit counter that counts in the sequence: 000, 101, 010, 011, 001, 110, repeat. Use Determine the next states of the unused states 100 and 111 SR flip-flops. 3. Design a decade counter that counts up 0000 to 1001, then repeats. Use T flip-flops for the design. Draw a complete state diagram that includes the unused states 1010 to 1111 and their next states. 4. Design a decade counter with the following weighted code for decimal digits: Digit IABCD 1 000 1 2 0010 3 0011 4 0 100 5 1011 6 1100 7 1101 8 1110 are available
