Using S arithmetic processing and the normal bandwidth characteristics of the S IF lter, the sound uality can be
made close to a conventional analog lter by rounding the shoulder of the lter, or importance can be placed on the lter
cut-off by making the skirt characteristics at. In addition, an improved lter composition can be enjoyed depending on
the mode by combining the passing bandwidth characteristics and attenuation band characteristics.

The following settings are available.
SHARP Set the passing bandwidth of the IF lter
as amplitude characteristic. Using
arithmetic processing, a sharp and ideal
shape factor will result.
Set the characteristic of the IF filter as a
SOFT
phase characteristic. Using S arithmetic
processing, the shoulder of the filter will
become rounded and the sound uality
will become close to that of a conventional
analog lter.
