FFTs during EDMR (before demodulation): (a) FFT of BM EDMR (red). The colormap represents the absolute value of the FFT during a BM with \(f_B\) = 5.1 kHz with a cross sections in blue (on resonance) and grey (off resonance = noise floor). (b) Zoom of BM EDMR revealing a large background signal at the demodulation frequency. (c) FFT of TM EDMR (cyan). TM with \(f_B\) = 500 Hz and \(f_{RF}=5.1~\text {kHz}\) leading to sideband in resonance. (d) Zoom of TM EDMR revealing the resonance peak far above the background noise.
