I've gone through the decoder truth table and able to understand that. but i want to know why the corresponding output values related to input values get 1.
Example if we consider 2 to 4 Decoder when inputs are 1 1 then the output will be 1 0 0 0 the 4th place will get 1.
I need a reason why this is happening ?
A line decoder is designed to turn code(encoded boolean values) into mutually-exclusive signals (only one of the outputs can be 1) as you can see from the decoder truth table. A schema and circuitry for the decoder is implemented using this truth table because that is the behavior we are trying to create in our circuitry.
