Nyquist Sampling Theorem

The Nyquist Sampling Theorem states that:

A bandlimited continuous-time signal can be sampled and perfectly reconstructed from its samples if the waveform is sampled over twice as fast as it's highest frequency component.

Nyquist limit: the highest frequency component that can be accurately represented:

$$f_{\mbox{max}} < f_s/2.$$

Nyquist frequency: sampling rate required to accurately represent up to $f_{\mbox{max}}$:

$$f_s > 2f_{\mbox{max}}.$$

No information is lost if sampling above $2f_{\mbox{max}}$.

No information is gained by sampling much faster than $2f_{\mbox{max}}$.

Is $f_s = 44,100$ Hz (CD-quality) enough?
