Question

Minimum hardware required to construct a $3\times 8$ decoder is using _______.

• A. Two $2\times 4$ decoders
• B. Two $2\times 4$ decoder and one $1\times 2$ decoder
• C. One $2\times 4$ decoder
• D. Depends upon the style of manufacturing

Answer 1

The correct option is B Two $2\times 4$ decoder and one $1\times 2$ decoder

Minimum hardware required to construct a 3×83×8 decoder is using a Two 2×42×4 decoder and one 1×21×2 decoder.

first let’s see how a 3 by 8 decoder It has 3 inputs, 8 outputs (well, pretty obvious statement coming from the name) but it also has 3 not operators and 8 with triple inputs.
