1. Show how to implement the 8-input multiplexers described below. In each case the three select input bits should be labeled s2, s1.So, with so being the least significant. Label the data inputs 0 to 7. a) Implement an 8-input multiplexer using four 2-input multiplexers and one 4- input multiplexer (as many as you need) b) Implement an 8-input multiplexer using two 4-input multiplexers and one 2- input multiplexer. 2. We have two 4-bit comparators that produce greater than (>), equal (-), and less than (
