Strong signal with \(f_1 = 5950 MHz\): a instantaneous frequency; b estimates of zero crossings as a function of Nyquist multiple \(N_M\); c difference between estimates of zero crossings and actual zero crossings as a function of \(N_M\); d estimates of the weak signal amplitude as a function of \(N_M\); e estimates of weak signal frequency as a function of \(N_M\); f difference between weak signal amplitude estimates and actual weak signal amplitude as a function of \(N_M\); g difference between weak signal frequency estimates and actual weak signal frequency as a function of \(N_M\); h relative error in the weak signal amplitude as a function of \(N_M\)
