1- Draw the schematic implements a 3-to-8 decoder using only 2-to-4 decoders and logic gates.

2- Design a counter that counts up when a control input w=1 and stays the same when w=0.
The upward sequence is 000, 001, 010, 011, 100, 101, 110, 111.

- Fill in the excitation-table for the counter with JK lip-flops.
