1i have read dis in computer science in class 12......havent seen in physics
23not electronics, but its an analogy to boolean algebra in electronics
its logic , as rahul mentioned
as we know abt 0 , 1
same in logic ,
0 = False =F
1=True =T
operations :
(1] ^ = and
2] v = or ,
3] ~ = negation i.e bar ,
4] \rightarrow = implies ,
5] \leftrightarrow = double implies
general rules
1] T \wedge F = F \wedge T = F
2] T \vee F = F \vee T = T
3] T\rightarrow F = F
4] F \rightarrow T = T
5] F \rightarrow F = T
6] T \rightarrow T = T
7] \sim T = F
8] \sim F = T
9] T \leftrightarrow F = F
10] F \leftrightarrow T = F
11] F \leftrightarrow F = T
12] T \leftrightarrow T = T
