Below are sample questions representative of the exercises included on this worksheet and related 8.77 Compare Analog and Digital Representations skill assessments:

Problem 1Difficulty: Mastery

Which statement best compares an analog volume knob inside an amplifier with a digital school alert sent as text to classrooms?

ABoth systems are analog because both involve electricity

BBoth systems are digital because both use devices

CThe knob uses continuous control, while the alert uses discrete coded symbols that are easier to send reliably

DThe text alert is analog because letters can be read

Solution & Explanation:An analog knob can vary continuously, while a digital text alert uses discrete symbols that are easier to transmit accurately to many rooms.

Problem 2Difficulty: Mastery

Two audio clips are sent over the same noisy network. One is represented as a continuously varying simulated voltage. The other is an encoded audio file. Which is more likely to reconstruct clearer speech at the receiver, and why?

AThe continuous simulated voltage, because continuous means clearer

BThe encoded audio file, because digital coding is usually more robust to small transmission noise

CBoth will always sound identical

DNeither can carry speech

Solution & Explanation:An encoded digital file is usually more robust because the receiver can work with discrete coded data rather than a continuously distorted signal.

Problem 3Difficulty: Mastery

A teacher shows the plot in the image. The temperature record is marked at equal time intervals and uses a limited set of step-like values. Which feature most strongly suggests digitization?

AThe fact that temperature can change

BThe use of a y-axis

CThe equal-time samples and limited allowed values

DThe presence of labels

Solution & Explanation:Sampling at regular times and using a limited set of values are strong signs of a digital record.
