Sampling Theorem
In order for a band-limited (i.e., one with a zero Power Spectrum for frequencies 
) baseband (
) signal to bereconstructed fully, it must be sampled at a rate 
. A signal sampled at 
is said to be NyquistSampled, and is called the Nyquist Frequency. No information is lost if a signal is sampledat the Nyquist Frequency, and no additional information is gained by sampling faster than this rate.
