Q:

How do you detect a sequence of "1101" arriving serially from a signal line?

Answer

A SIPO and AND gate circuit can detect this sequence.The output of SIPO is connected to a four input AND gate ,the third SIPO output should be connected through a NOT gate.When the 1101 sequence is loaded in to the SIPO the AND output goes HIGH otherwise keeps LOW.

A) 9 B) 6
C) 5 D) 4
 
Answer & Explanation Answer: D) 4

Explanation:

Let the value to be find be 'x'.

 
Sum of individual column value = 14

 
C1 = 7 + 2 + 1 + 4 = 14
C2 = 3 + 8 + 1 + 2 = 14
C3 = 6 + 5 + 2 + 1 = 14
