DIGITALLY TUNED VARIABLE FILTER
Information
The Models 3320
3321
3322 and 3323 Filters illustrated in
Figure 1, are variable, electronic Filters with digitally
tuned cutoff frequencies". The Models 3320 and 3322 have a
cutoff frequency range from 0, 001 Hz to 99. 9 kHz. The
Models 3321 and 3323 are tunable over the range from 0, 01
Hz to 99. 9 kHz. The pass-band gain is unity (Odb) or 10
(20db), with attenuation rates of 24db per octave outside
the pass-band. Maximum attenuation is greater than 80db and
the output hum and noise is less than 500 microvolts. The
Model 3320 (Model(3321) can function as either a High-Pass
or Low-Pass Filter, In the High-Pass mode of operation the
maximum input signal is plus or minus 7 volts peak in the
Odb gain position, plus or minus 0. 7 volts peak in the 20db
gain position, and the upper 3db point occurs at
approximately 1 MHz. In the Low-Pass mode the Filter is
direct-coupled and the combined ac plus dc input signal
should not exceed ±1 volts peak in the Odb gain position and
±0. 7 volts peak in the 20db gain position.
The Model 3322 (Model(3323) consists of two of the Model
3320 (Model 332 1) mounted in a single cabinet isolated from
each other, with independent power supplies and input and
output connectors. When these two Filter channels are
switched to the same mode of operation and cascaded, with
both channels set to the same cutoff frequency, the Model
3322 (Model(3323) will function as a High-Pass or Low- Pass
Filter with an attenuation rate of 48db per octave. If the
two channels are connected in series, and one channel is
operated in the Low-Pass mode and the other channel in the
High-Pass mode, the Model 3322 (Model(3323) will function as
a Band-Pass Filter with an attenuation rate of 24db per
octave outside the pass-band. W'hen the two channels are
connected in parallel, as described in Section 2.3, the
Model 3322 (Model(3323) will function as either a
Band-Reject Filter with cutoff frequency limits from 0. 00 1
Hz to 99.9 kHz (0.01 Hz to 99.9 kHz - Model(3323) or provide
a null at any frequency between 0. 01 Hz and 10 kHz (0. 1 Hz
and 10 kHz - Model(3323).
The Filter has a maximally flat (Butterworth) characteristic
when the FUNCTION switch(s) is in the Low-Pass MAX FLAT
position. For pulse-type wave-forms this switch should be in
the Low-Pass RC (Low Q) position, optimum for transient-free
filtering.
