It is the principle to accurately reproduce a pure sine wave measurement, or sample, rate, which must be at least twice … Web1 Answer. Well, have a look at the statement of the theorem - it assumes that the signal is band-limited i.e. it has finite frequency content, so the first integral over ( − ∞, ∞) reduces to a finite integral over [ − 2 π W, 2 π W] because the signal contains no frequencies larger than W. Intuitively, you need this assumption because ... earth swale
