Question

Which of the following represents a number of output lines for a decoder with 5 input lines?
A. 31
B. 10
C. 32
D. 25​

Answer 1

Answer:

B

Explanation:

But, I am not sure!5 input+5 output lines.

Answer 2

The number of outputs for 5 input lines in a decoder is equal to 32

• The combinational circuit that change the binary information into  $2^{n}$output lines is known as Decoders.
• The binary information is passed in the form of N input lines. The output lines define the $2^{n}$-bit code for the binary information. In simple words, the Decoder performs the reverse operation of the Encoder.
• At a time, only one input line is activated for simplicity. The produced $2^{n}$-bit output code is equivalent to the binary information.

Hence , the number of inputs here is 5

Therefore number of output lines is  $2^{5}$

                                                        ⇒ 2*2*2*2*2

                                                       ⇒ 32

Answer : c) 32
