Consider the circuit in Figure 1. It is a 4-bit (QQ2Q3) synchronous counter which uses four T-type flip-flops. The counter increases its value on each positive edge of the clock if the Enable signal is asserted. The counter is reset to 0 by setting the Clear signal low. You are to implement an 8-bit counter of this type Enable T Q Clock Clear Figure 1. 4-bit synchronous counter (but you need to implement 8-bit counter in this lab) Specific notes:...

1. Suppose you want to design a 2-bit binary up-counter. Construct the state table using A1 and AO as the previous state of bits and A1+, A0+ as the next bit states, ie, to count from 00 to 01, A1 stays at 0, but AO changes from 0 to 1. Let the counter wrap-around, such that 11 -> 00. Draw the state diagram. 2. Next, add in a third input, En, for enable. The counter can only count up when...
