In the example shown in Figure 70, the Current Level marker shows that Stereo % is 50%. Multipath threshold is
programmed as: 60% (and above) for full mono and 20% (and below) for full stereo. Multipath reported by the part
is 11% which would put the part in full stereo. However the final blend percentage is determined by SNR and the
stereo level is 56%. The graph shows the current state of Multipath(green diamond), RSSI (white diamond) and
SNR (yellow diamond) and plots for each of them that show the transition between high and low thresholds and
how the blend would be adjusted accordingly. You can adjust the configuration values to see how these plots and
the current state of blend would change.
