this interval becomes 0 < f < ∞, of course. We follow Gardner’s terminology in the
following and use one-sided spectra only.
Noise analysis is explained by Fig. 4.4, in which input signal and input noise are plotted
once again. Here, we assumed for simplicity purposes that the input signal consists of one
spectral line at the down-scaled center frequency f ′.
