Figure 2.

Experimental data example 1—results of NERD at 16- and 4-scan cw-ESR spectra with the SNR at individual peaks in Table 1. (a) 16-scan noisy signal overlapped with its denoised signal, (b) denoised signal of the 16-scan noisy signal overlapped with the reference signal, (c) 4-scan noisy signal overlapped with its denoised signal, and (d) denoised signal of the 4-scan noisy signal overlapped with the reference signal. P1 is peak 1.
