High Cut
bar graph – Audio disturbance effect is generally present in the high frequencies.
Therefore, a means of reducing the effect of disturbances is to filter the high frequencies. The
audio bandwidth reduction is called “high cut”. A value of 100% indicates that no “high cut” is
applied. The applied High Cut level depends on the following input signals: RF Signal Level,
Multipath and Ultrasonic Noise.
