Description
Information
                                    The Model 3103(H), illustrated in Figure 1, is a solid state
variable electronic band-pass Filter with a low cutoff
frequency range adjustable continuously from 10 Hz to 1 MHz
and a high cutoff range from 30 Hz to 3 MHz. The pass-band
gain is unity (0 db), with attenuation rate of 24 db per
octave outside the pass-band, and a maximum attenuation of
80 db. Maximum input signal amplitude is 3 volts rms and
output hum and noise is less than 150 microvolts.
As shown in the Simplified Schematic Diagram, Figure 2, the
Filter consists basically of an input amplifier, a variable
low-pass section (high cutoff frequency), and a variable
high-pass (low cutoff frequency) section all connected in
series. Both cutoff frequencies are tuned capacitively in
decade steps by the band multiplier switch, and continuously
within each decade by the frequency dial which varies four
cascaded resistorfilter elements. A response switchS 1
selects the desired filter characteristics.
