NAND
F3 = F1 NAND F2;F3 is OFF if F1 and F2 are ON; otherwise, F3 is ON
F1 F2 F1 NAND F2
OFF OFF ON
OFF ON ON
ON OFF ON
ON ON OFF
OR
F3 = F1 OR F2;F3 is ON if either F1 or F2 are ON; otherwise F3 is OFF
F1 F2 F1 OR F2
OFF OFF OFF

ON OFF ON
ON ON ON
NOR
F3 = F1 NOR F2;F3 is OFF if either F1 or F2 are ON; otherwise F3 is ON
F1 F2 F1 NOR F2
OFF OFF ON
OFF ON OFF
ON OFF OFF
ON ON OFF
XOR
F3 = F1 XOR F2;F3 is ON if F1 and F2 are different
;F3 is OFF if F1 and F2 are the same
F1 F2 F1 XOR F2
OFF OFF OFF
OFF ON ON
ON OFF ON
ON ON OFF
NOT
F3 = NOT F1;F3 is ON if F1 is OFF; F3 is OFF if F1 is ON
F1 F1 NOT F2
OFF ON
ON OFF
Examples
F2 = F4 AND I11
F2 = F4 OR I11
F10 = F1 XOR F12
F7 = ATHOME NAND F3
F7 = I9 NOR F11
O1 = I7 AND I8 AND NOT I9
O1 = NOT F3
