Module 2.1 – Fundamentals (Sampling)


  • discretization of signals in time
  • sampling ambiguity and aliasing
  • sampling theorem

1. Is the following statement true or false? “Perfect reconstruction of a continuous signal is always possible as long as its bandwidth is lower than the sampling rate.”


2. What is the maximum bandwidth of a continuous signal that allows (theoretically) the perfect reconstruction of the signal when sampled at a rate of 44.1kHz?


3. Mark all of the frequencies of a continuous sinusoidal input signal the will result in a 1kHz digital sinusoidal signal when sampled at 6kHz.


4. Why are typical sampling rates for speech lower than typical sampling rates for music?
