Digital Filters for Video Processing  click here for printable datasheet

  • Designed for Analog and Digital Video Filtering
  • Band Limiting of Video SignalsVery Low Distortion Due to the Tight Control of Delay in the Passband
  • Fast Transition from Passband to Stopband along with Good Stopband Rejection to over 100 MHz
  • Also Used as Anti-Aliasing Pre Filters befor Analog to Digital Converters
  • When used as Post-Aliasing Filters in Digital Processing Applications, the Passband can be shaped to correct for sin x/x (See VSL series)
