The logic shown in the given figure works as:a)decoderb)binary to XS-3...
Priority encoder:-
If more than one input is high then encoder produce an output which may not be correct to overcome this we use priority encoder.
We considered one more output, V in order to know, whether the code available at outputs is valid or not.
If at least one input of the encoder is ‘1’, then the code available at outputs is a valid one. In this case, the output, V will be equal to 1.
If all the inputs of encoder are ‘0’, then the code available at outputs is not a valid one. In this case, the output, V will be equal to 0.
Analysis:-
Logic shown in given figure will work as
Priority encoder (4 × 2)
Inputs = D3, D2, D1, D0
Output:
y = D3 + D2’ D1
X = D3 + D2
V = D3 + D2 + D1 + D0
