Question

Pick out the wrong statement

• A. Analog signals provide a continuous set of values
• B. Digital signals represent values as discrete steps
• C. Analog signals cannot utilize the binary system
• D. Digital signals can be processed by logic gates
• E. Digital signals can utilize decimal as well as binary systems

Hint:

Digital electronics is based on binary logic.

Answer 1

Answer: (E)

Concept: Analog vs Digital signals.

Step 1: Evaluate statements.

• Analog → continuous → correct
• Digital → discrete → correct
• Analog cannot use binary → correct
• Digital processed by logic gates → correct

Step 2: Check incorrect.
Digital systems fundamentally use binary (0 and 1), not decimal directly.

Step 3: Conclusion. \[ \boxed{(E)} \]
