Sampling — A First Look at the Nyquist Rate

Inside this lesson
  • State the Nyquist sampling criterion: f_s ≥ 2 × f_max
  • Define the Nyquist rate as 2 × f_max
  • Describe aliasing qualitatively as the phenomenon where distinct frequencies become indistinguishable after sampling
  • Apply the Nyquist criterion to practical scenarios such as digital audio
