Intro to Computing - How Data is RepresentedA student wrote that quantization converts digital signals back to analog. What is the error in this statement?AQuantization converts analog signals to digital, not the reverseBQuantization compresses digital signalsCQuantization removes noise from analog signalsDQuantization is the same as samplingCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand quantization's roleQuantization assigns discrete digital values to sampled analog signals; it does not convert digital back to analog.Step 2: Identify the incorrect claimThe 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:Confusing quantization with DACThinking quantization compresses dataMixing quantization with sampling
