1. The 4221 code is a base 10-oriented code that assigns the weights 4221 to each of 4 bits in a nibble of data. Design a logic circuit that takes a BCD nibble as input and converts it to its 4221 equivalent. The logic circuit should also report an error in the BCD input if its value exceeds 1001.
2. The 4-bit digital output of each of two sensors along an assembly line conveyor belt is proportional to the number of parts that pass by on the conveyor belt in a 30-s period. Design a logic circuit that reports an error if the outputs of the two sensors differ by more than one part per 30-s period.
b. What is the minimum expression for the function?
c. Realize the function using a 1-of-8 multiplexer.
Two equal masses are connected on either side of a pulley. One of the masses rests on an inclined plane with angle of inclination of b. The other one hangs in mid air.
