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)
