medium📝 Analysis Q6 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand quantization's role
Quantization assigns discrete digital values to sampled analog signals; it does not convert digital back to analog.Step 2: Identify the incorrect claim
The statement wrongly claims quantization converts digital to analog, which is false; that is done by Digital-to-Analog Conversion.Final Answer:
Quantization converts analog signals to digital, not the reverse -> Option AQuick Check:
Quantization = analog to digital value assignment [OK]
Quick Trick: Quantization assigns digital values to analog samples [OK]
Common Mistakes:
MISTAKES- Confusing quantization with DAC
- Thinking quantization compresses data
- Mixing quantization with sampling
