Questions
Yоu аre cоnsidering the purchаse оf а new piece of equipment, “Model A”, that costs $600,000, and will be depreciated using four-year straight line depreciation over the course of the four year project. The equipment requires 20,000 in annual maintenance, and will be sold for $80,000 at the end of four years. If your effective tax rate is 20%, what will be the effective cost of this machine? Your WACC is 10% on equipment purchases.
10. In this prоblem yоu will design а series оf decoder devices. а) Drаw a functional block diagram for a 1-to-2 decoder with active-high input X, active-low outputs Ya, an active-low enable (labeled E1) and an active-high enable (labeled E2). These are NOT a tri-state enables. Use the normally used subscripts for the two Y outputs (Y0 and Y1). b) Draw a functional block diagram for a 2-to-4 decoder with active-high inputs Xa, active-low outputs Yb, an active-low enable (labeled E1) and an active-high enable (labeled E2). These are NOT a tri-state enables. Use the normally used subscripts for the two X inputs (X0 and X1) and the four Y outputs (Y0 through Y3). c) Draw a functional block diagram for a 3-to-6 decoder with active-high inputs Xa, active-low outputs Yb, and no enable. Use the normally used subscripts for the three X inputs (X0 through X2) and the six Y outputs (Y0 through Y5). d) Design a 3-to-6 decoder using one 1-2 decoder and the minimum number of 2-to-4 decoders (as drawn in parts a and b) and no other device(s). (If necessary, also use SSI gates for much less credit.) e) How can you modify the circuit in part d to give the 3-to-6 decoder an active-low enable, G(L)? Add this new circuit IN A BOX to your previous solution to part d.
