In my digital logic lecture today, my professor introduced a symbol code called Patty Code. I copied this table off the whiteboard:
| Symbol | Binary | Odd Patty | Even Patty | |--------+--------+-----------+------------| | a | 00 | 100 | 000 | | b | 01 | 001 | 101 | | c | 10 | 010 | 110 | | d | 11 | 111 | 011 |
I did try Googling for both "patty code" and "patti code" with nothing substantial.
I asked my professor after lecture what is Patty Code. He said it's used occasionally. I asked him if it's another name for excess-3 or grey code, to which he said it is different to both of those codes.
Is my professor yanking my class's chain, or is this actually a real code?
I want to leave record that the professor that gave me this misconception has a relatively strong accent. He is very knowledgeable and always gives me a satisfactory answer to EE related questions. So I finished that class, and am happy with the result. Hopefully nobody else has to Google this question!
