Simplify the functions described below using K-maps, draw circuit diagram for simplified functions and show truth tables. 1. F, (I, J, K)= (m,m,,m,,m) 2. F2 (A, B, C, D)= (m,,mz,m,,ms,m,m,,m,,,m,2,m.) 3. F3 (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. F4 (A, B, C, D)= |(M,,M3,M,,M,)(hint: convert to minterm expression first)
