HIGHPASS / LOWPASS / NOTCH FILTERS

Encore offers several analog filters for noise reduction and anti-aliasing applications. Unity gain in the passband is standard, although the Model 721M adds a switch-selectable gain of 1, 10, or 100. Response can be Butterworth or Bessel upon request. Switch-selectable frequency cutoffs are typically customer-specified.
