Switching function of the network is...

Switching function of the network is

A

`(a+b).c+(a'+b'+c')`

B

`(a+b).c.(a'+b'+c')`

C

`(a.b)+c+(a'.b'.c')`

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B
Since, switches a, b and a',b',c' parallel which is denoted by `a+b` and `a'+b'+c'` respectively.
Now `(a+b),c" and "(a'+b'+c')` are connected in series, then switching function of complete network is
`(a+b)c(a'+b'+c')`
