Block diagram:
 |
m (<= 2n) inputs |
|
n outputs |
|
Design assumes that only one input is on (logic 1) at any time |
|
If more than one input is 1, then behavior is undefined |
|
If no inputs are 1 (all 0's), then behavior is undefined |
Consumes minterms, rather than producing them...
so, generally less useful for our logic design purposes.
Get rid of the ambiguities of the vanilla encoder
|
If two or more inputs are 1, the higher-order bits take precedence |
|
Add a V (for valid) output, that is set to 0 if all inputs are 0 |
