• Soft Mute—Improves the user experience by dynamically muting the output audio proportionate to the
FM signal C/N. This prevents the user from being assaulted with a blast of static. The mute characteristic is
fully programmable to accommodate fine tuning of the output signal level. An example mute
characteristic is shown in Figure 23.
