Figure 67. FM Configuration Helper Window (Softmute)
In the example shown in Figure 67, the current level marker shows that Soft Mute level is 0 dB. SNR threshold is
programmed as 4 dB and max attenuation is 16 dB. Since the SNR reported by the part is 5 dB, which is above the
threshold, the softmute level is 0 dB. The graph shows the current state of SNR (green diamond) and plot shows
the softmute profile based on max attenuation, threshold and slope settings. You can adjust the configuration
values to see how the plot and the current state of softmute would change.
