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
