Third, we compared the DNN-DRT model against the DRTtools for 𝑁 = 𝑀 using the separated 2 × ZARC model with peaks of different heights. The DNN-DRT model outperformed the DRTtools for the DRT recovery (see 𝜀 , in Table ) and led to a similar impedance recovery (𝜀̅ , in Table ), which we also noted graphically (Figure ).
