Reference no: EM13226203
Design a circuit that will add either 1 or 2 to a 4-bit binary number N. Let the inputs N3, N2, N1, N0 represent N. The input K is a control signal. The circuit should have outputs M3, M2, M1, M0, which represent the 4-bit binary number M. When K = 0,M = N + 1. When K = 1, M = N + 2. Assume that the inputs for which M > 11112 will never occur.
Design the circuit using only two-, three-, and four-input NAND gates and inverters. Try to minimize the total number of gates and inverters required. The input variables K, N3, N2, N1, and N0 will be available from toggle switches. Any solution that uses 13 or fewer gates and inverters (not counting the five inverters for the inputs) is acceptable.
include truth tables, k maps, and pos/sop equations

Compute the number of clock cycles required to execute
: 1- Describe the function of the program. DO NOT WRITE THE OPERATION OF EACH INSTRUCTION 2- Assuming that the branch instruction is executed (the branch is taken), comput the number of clock cycles required to execute the loop (DECA or BNE AGAIN)

Explain isoamyl acloho to make isoamyl acetate
: You will start with 500 mg of one of isoamyl acloho to make isoamyl acetate. While the alcohols are liquids, we will measure them by mass directly on the balance, not by volume (i.e. the density of the alcohol will not be used; pretend the alcohol..

Compute the mass of sulfuric acid
: The sulfur is converted first to SO2, which reacts with oxygen and atmospheric moisture to produce sulfuric acid, H2SO4. If a particular coal contains 0.95% sulfur (by mass), calculate the mass of sulfuric acid produced by burning a metric ton (10..
