💡 Hint

Common Mistakes

Confusing digital with analog signals

Thinking digital signals are continuous

A digital signal uses discrete values, typically 0s and 1s, to represent information.

2fill in blank

💡 Hint

Common Mistakes

Choosing discrete instead of continuous

Mixing up digital and analog terms

Analog signals change smoothly and continuously over time, unlike digital signals.

💡 Hint

Common Mistakes

Confusing analog with digital

Thinking digital signals are continuous

Digital signals are discrete, meaning they take specific values, not any value within a range.

4fill in blank

hard

Fill both blanks to complete the comparison between analog and digital signals.

Computer Networks

Analog signals are [1], while digital signals are [2].

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up continuous and discrete

Choosing random or constant incorrectly

Analog signals change continuously, digital signals change in discrete steps.

5fill in blank

hard

Fill all three blanks to complete the sentence about signal conversion.

Computer Networks

To convert an analog signal to digital, we use [1]; to convert digital back to analog, we use [2]; the process involves [3].

Aanalog-to-digital converter

Bdigital-to-analog converter

Csampling

Dmodulation

💡 Hint

Common Mistakes

Confusing ADC and DAC

Choosing modulation instead of sampling

An analog-to-digital converter (ADC) changes analog signals to digital. A digital-to-analog converter (DAC) does the reverse. Sampling is the process of measuring the analog signal at intervals.
