The Krohn-Hite Model 3945 programmable
filter provides one Butterworth channel of
low-pass, tunable over the range from 170Hz to 25.6MHz; and two independent Butterworth or Bessel channels of
low-pass, high-
pass or bypass, one channel of band-
pass or band-reject, tunable over the range from 3Hz to 2MHz. The 3945 has been specifically designed for applications requiring high
frequency band-
pass filtering. The high cutoff may be set to any
frequency between 170Hz and 10MHz, and the lower cutoff...
