What is the primary distinction between analog and digital signals?
Analog signals are faster than digital signals
Digital signals are always more accurate
Analog signals are continuous while digital signals are binary (0 or 1)
Digital signals cannot be transmitted over long distances
In modern digital circuits, which technology is most commonly used due to its advantages?
Transistor-transistor logic (TTL)
Complementary Metal-Oxide-Semiconductor (CMOS)
Emitter-coupled logic (ECL)
Bipolar junction transistor (BJT)
What is the main advantage of digital systems in terms of signal recovery?
Digital signals never get corrupted
Digital signals can be easily recovered using a comparator even when corrupted
Digital signals don't require any processing
Digital signals have infinite bandwidth
What is the output of a NAND gate when both inputs are 1?
1
Depends on the voltage level
0
Cannot be determined
According to De Morgan's theorem, what is equivalent to (A + B)'?
A' + B'
A' · B'
(A' + B')'
A + B'
Which of the following is NOT a primary advantage of digital systems?
Data can be stored in various media
Functionality can be programmed
Signals cannot be corrupted during transmission
Computers can process the data
For an XOR gate, under what condition is the output 1?
When both inputs are 1
When both inputs are 0
When both inputs are the same
When inputs are different
What does the distributive law state for Boolean algebra?
A · (B + C) = (A · B) + (A · C)
A + (B · C) = (A + C) · (A + B)
A · (B + C) = A + (B · C)
(A + B) · C = A · C + B
In digital circuits, what voltage levels typically represent logic 0 and logic 1 respectively?
-5V and +5V
0V and 3.3V
0V and 5V
-12V and +12V
Which of the following is a correct application of the principle of duality?
Converting AND to OR only
Converting 1s to 0s only
Converting AND to OR and 1s to 0s simultaneously
Converting variables to their complements
