What does the term 'discrete-time signal' refer to?
💡 Hint: Think about how we measure time.
True or False: The Nyquist rate is the minimum sampling rate to avoid aliasing.
💡 Hint: Relate this to what happens when sampling is inadequate.

Challenge Problems
Push your limits with advanced challenges
A continuous signal is sampled at 1.5 kHz. If this signal has frequency components up to 800 Hz, analyze whether aliasing may occur.
💡 Hint: Use the Nyquist theorem to assess the sampling rate.
Derive the discrete representation x[n] for a continuous signal x(t) = sin(2π300t) when sampled at 0.002 seconds.
💡 Hint: Substitute the value of t with n times the sampling period.
