Abstract : The Nyquist frequency is half the sampling frequency when a continuous-time function is sampled at equally spaced time points. That is, the Nyquist frequency is pi/delta (in radians per unit time) where delta is the time interval between two successive sampled data. This report discusses the basic ideas of the Nyquist frequency and explains its relationship between aliasing and the sampling theorem.
