Question 1

What is a primary characteristic of continuous-time signals?

They exist at specific intervals
They are defined for every instant of time
They cannot be processed digitally

💡 Hint: Think about how you can visualize these signals.

Question 2

True or False: An analog signal can take on any amplitude value in a continuous range.

True
False

💡 Hint: Remember the definition of analog versus digital.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Suppose you have a continuous signal that you convert into discrete-time. Describe how the frequency content of the original signal is affected by aliasing.

💡 Hint: Think about the consequences of sampling rates and how they interact with the frequencies present.

Challenge 2 Hard

Given a periodic signal with a known fundamental frequency, how would you derive its Fourier series representation? Explain your steps.

💡 Hint: Review the Fourier series definitions and how coefficients are calculated.
