Hands-on Component

Students will be given programming assignments to gain a better understanding of the theoretical concepts.

Learning Outcomes

  1. Learn to sample a continuous-time signal without loss of any information and recover the signal from the samples.
  2. Understanding of analytical tools such as DTFT, DFT, and FFT, and ability to use them for the frequency-domain analysis of signals.
  3. Ability to design and implement digital filters to meet design requirements.
