Model predictions for the BM gain in the active case (80% activity). As in Ref. 19, the gain is normalized to the maximum passive model gain. Thin solid line: Active LR model response. Thick dashed line: Active TM-LC model response. Thin dashed line: Active BM-LC model response. Thick solid line: Active TMBM-LC model response. The values for ϵ₃(x) for the different models are given in Table 3. The four models are capable of predicting realistic maximum gains but at these activity levels the Q_{10 dB} for the LR and BM-LC models are always much higher than that predicted by the TM-LC and TMBM-LC models.
