Represent the following circuit into the symbolic form and write down the input, output table or switching table
​

Answer 1

Answer: Let pp : the switch S1S1 is closed

Let qq : the switch S2S2 is closed

Let rr : the switch S3S3 is closed

∼p∼p : the switch S′1S1′ is closed or the switch S1S1 is open

∼q∼q : the switch S′2S2′ is closed or the switch S2S2 is open

∼r∼r : the switch S′3S3′ is closed or the switch S3S3 is open

ll : the lamp L is on

The symbolic form of the given circuit is:

(p∨q)∧q∧(r∨∼p)(p∨q)∧q∧(r∨∼p)
