Signal Processing — Quiz

Test your understanding of signal processing with 5 practice questions.

Practice Questions

Question 1

When analyzing a discrete-time signal, what is the primary consequence of violating the Nyquist-Shannon sampling theorem?

Question 2

A digital filter is designed to remove a narrow band of frequencies around $50 \text{ Hz}$ from a signal. Which type of filter would be most appropriate for this specific task?

Question 3

In the context of practical signal conditioning for sensors, what is the primary role of an 'instrumentation amplifier'?

Question 4

Consider a discrete-time signal $x[n]$ with a sampling rate of $f_s = 200 \text{ Hz}$. If the signal contains a frequency component at $150 \text{ Hz}$, what apparent frequency will be observed due to aliasing if no anti-aliasing filter is used?

Question 5

When performing a Fast Fourier Transform (FFT) on a finite-duration signal, what is the primary consequence of 'spectral leakage'?
