1.	For 8-bit input encoder how many combinations are possible?(a) 8(b) 2^8(c) 4(d) 2^4I got this question in examination.The above asked question is from Encoders in portion Combinational Circuits of Digital Circuits
Answer» Correct answer is (b) 2^8 For explanation: An encoder is a COMBINATIONAL circuit encoding the information of 2^n INPUT lines to n OUTPUT lines, thus producing the binary equivalent of the input. There are 2^8 COMBINATIONS are possible for an 8-bit input encoder but out of which only 8 are used USING 3 output lines. It is a disadvantage of encoder.
