ANALYSIS OF DISCRETE TIME SIGNAL Quiz

Question 1: What is sampling of signals?

• Converting a continuous-time signal into a discrete-time signal by taking samples at regular intervals

• Measuring the frequency of a signal

• Converting a digital signal into an analog signal

• Transforming a discrete-time signal into a continuous-time signal

Question 2: Why is sampling important in signal analysis?

• To convert continuous-time signals into discrete-time signals for easier processing and analysis.

• To make the signal more complicated

• To make the signal less accurate

• To slow down the processing and analysis
