Task 1120 marks Simplify the functions described below using K-maps, draw circuit diagram for simplified functions and show truth tables. 1. F, (1, J, K) = E (m,,m,,m,,m,) 2. F: (A, B, C, D) - E(m,, m, , m, m, , m,,m,, mm m,) 3. F: (X, Y, Z, W) - for input of numbers in [0, 15] as binary bits, the output is high when input is a prime number and is low otherwise. 4. F, (A, B, C, D) = [|(M,,M,,M M,) (hint convert to minterm expression first)
