WebbMany practical obstacles stand in our way and we can rarely achieve Shannon’s capacity. We ﬁrst state the simplest case as theorized by Nyquist. In 1927, Nyquist developed a thesis that in order to reconstruct a signal from its samples, the analog signal must be sampled at least two times its highest frequency. From this comes the ideas that WebbIn texts that introduce the Shannon capacity, bandwidth W is often assumed to be the half-power frequency, which is closely related to MTF50.
