Description
1 Select Parameter
Selects between Hi-cut Multipath (Si4706/4x only), Hi-cut SNR(Si4706/
4x only), SoftMute, Stereo blend Multipath (Si4706/4x only), Stereo
Blend RSSI and Stereo Blend SNR (Si4706/4x only).
2 Hi-cut/ Blend/Soft Mute Graph
The plot displays the device threshold and rate settings, current signal
conditions, and the calculated audio conditioning.
3 Plot Legend
The plot legend includes numeric values for current signal conditions
and calculated audio conditioning.
4 Configuration Values
Configure threshold and rate properties. These values are at all times
synchronized with the values available through the Properties window.
5 Selected Parameter Description Read a detailed description of the currently selected parameter in the
Configuration Values group.

In the example shown in Figure 65, the current level marker shows that Hi-cut filter is set at 6 kHz. This is
determined by both SNR and multipath conditions. Current SNR is 5 dB. Hi-cut SNR Low Threshold is set at 15 dB
and hi-cut minimum frequency is set at 6 kHz. SNR is the determining factor in this case as it is already lower than
the low threshold. Graph shows the current state of SNR (white diamond) and multipath (green diamond) and plots
for each of them that show the transition between high and low thresholds and how the hi-cut filter frequency would
be adjusted accordingly. You can adjust the configuration values to see how these plots and the current state of hi-
cut would change.
