Nyquist frequency signal, whereas "Nyquist frequency" is a property of a discrete-time system. When the function domain is time, sample rates are usually expressed in samples per second, and the unit of Nyquist frequency is cycles per second (hertz). When the function domain is distance, as in an image sampling system, the sample rate might be dots per inch and the corresponding Nyquist frequency would be in cycles/inch. Referring again to Figure 1, undersampling of the sinusoid at 0.6 f is what allows there to be a lower-frequency "alias", which is a different function that produces the same set of samples. That
Santander Cycles year is not available. A credit or debit card can be used in a docking station to release a bicycle. Access for 24 hours or 7 days can be purchased. Cycles may be rented at any time during the access period; use for no more than 30 minutes at a time is free of charge. Usage charges, additional to the access charge, are weighted to favour shorter use. Bicycles may be used any number of times within the access period, each use charged according to its duration. The original bicycles were built by Cycles Devinci to the following specification: The
