WebThe maximum frequency that can be unambiguously represented by digital data is (known as Nyquist frequency) when the samples are real numbers, and when the samples are complex numbers. [1] The normalized values of these limits are respectively 0.5 and 1.0 cycles/sample. This has the advantage of simplicity, but (similar to natural units) there ...
