Question
For the given logic circuit, which of the following inputs combination will make both LED-1 and LED-2 to glow?
Options
A.$A = 0,\text{ }B = 1,C = 1$
B.$A = 1,\text{ }B = 0,C = 0$
C.$A = 1,\text{ }B = 0,C = 1$
D.$A = 1,\text{ }B = 1,C = 0$
Solution
Sol. [Key Concept: Trace the OR then AND gate outputs; find the $A,B,C$ combination that makes both LED nodes read logic 1.]
