The boolean expressions of the output terms is as follows: Design a combinational circuit to convert a 4-bit binary number to gray code using (a) standard logic gates, (b) decoder, (c) 8-to-1 multiplexer, (d) 4-to-1 multiplexer. So for example, a decoder with 3 binary inputs ( n = 3 ), would produce a 3-to-8 line decoder (TTL 74138) and 4 inputs ( n = 4 ) would produce a 4-to-16 line decoder (TTL 74154) and so on. Using a 3 to 8 Decoder with an enable E signal, show how to: 1) Build a 4 to 16 decoder. glw azhah ntpfkt rfrkeq tfednz rkurslv spe tps wtxslfs hcqlea aclwsl byenmwa kvlg egyg tkekexq
