Video Gaussian Filters - Series VGF

vgfPrinter
  • Pulse Shaping 
  • Bandwidth Limiting
  • Remove unwanted distortions caused by ringing, preshoot and overshoot.
  • Temperature: 0 - 105 C
  • Fine Impulse Response: May be  used with delay lines requiring minimum pulse distortion in the delayed output.
  • Size: See drawing below
These filters are used for pulse shaping and bandwidth limiting. They are very useful in the removal of unwanted distortions caused by noise, ringing, preshoot and overshoot. Due to their fine impulse response, they are often used in conjunction with delay lines that must have minimum distortion in the delayed output.
