Functional Description
range (–
dB and others are also possible). Respectively two bytes are coded in the
CRAM to set GZ to the desired value. On reset, the GZ-gain stage is disabled (–
dB).
A high-pass filter (HPR) is also provided to remove disturbances from 0 to 50/60 Hz due
to the telecommunication network.
The FR-frequency correction response filter is similar to the FX-filter allowing an
optimum adaptation to different types of loudspeakers or earpieces. Twelve bytes are
necessary to set FR to the desired frequency correction function. On reset, the
FR-frequency correction filter is by-passed.
The GR-gain adjustment stage is digitally programmable from – 6 to 0 dB in steps
0.25 dB (–
dB and others are also possible). Respectively two bytes are coded in the
CRAM to set GR to the desired value. On reset, the GR-gain stage is by-passed.
A low-pass EWDF-filter limits the signal bandwidth in the receive direction according to
CCITT and ETSI (NET33) recommendations.
A series of low-pass interpolation filters increases the sampling frequency up to the
desired value.The last interpolator feeds the D/A-converter.
