DESCRIPTION
The SSI 32F8030 Programmable Electronic Filter pro-
vides an electronically controlled low–pass filter with a
separate differentiated low–pass output. A seven–
pole, 0.05
°
Equiripple-type linear phase, low–pass
filter is provided along with a single-pole, single-zero
differentiator. Both outputs have matched delays. The
delay matching is unaffected by any amount of pro-
grammed high frequency peaking (boost) or band-
width. This programability, combined with low group
delay variation makes the SSI 32F8030 ideal for use in
many applications. Double differentiation high fre-
quency boost is accomplished by a two–pole, low–
pass with a two–pole, high–pass feed forward section
to provide complementary real axis zeros. A variable
attenuator is used to program the zero locations, which
controls the amount of boost.
The SSI 32F8030 programmable boost and bandwidth
characteristics can be controlled by external DACs or
DACs provided in the SSI 32D4661 Time Base Gen-
erator. Fixed characteristics are easily accomplished
with three external resistors. In addition, boost can be
switched in or out by a logic signal.
The SSI 32F8030 requires only a +5V supply and is
available in 16-Lead SON, and SOL packages.
