The Nyquist criterion described in cylindrical surface spectrum: (a) the analog spectrum of a baseband signal whose highest frequency is lower than half of the sampling frequency; (b) the corresponding cylindrical surface spectrum of (a) after sampling; (c) the analog spectrum of a baseband signal whose highest frequency is higher than half of the sampling frequency; (d) the corresponding cylindrical surface spectrum of (c) after sampling
