However, this is not a necessary condition [BD98], as it is possible to admit a frequency f h above the Nyquist frequency instead of a frequency f b below the Nyquist frequency, if the difference between f b or f b and f h is an arbitrary multiple of the sampling frequency. Fig. 10.6 shows an example, where exact reconstruction of the green ....
