A 3-D integrator-differentiator double-loop (IDD) filter for raster-scan video processing

A novel RC-active circuit is proposed for the selective filtering of moving objects in raster-scanned analog video signals on the basis of their velocities. It consists of a feedforward continuous-time integrator and a two feedback loops with discrete-time differentiators in each loop. It has a freq...

Zusammenfassung:A novel RC-active circuit is proposed for the selective filtering of moving objects in raster-scanned analog video signals on the basis of their velocities. It consists of a feedforward continuous-time integrator and a two feedback loops with discrete-time differentiators in each loop. It has a frequency-planar passband in the 3-D space-time frequency domain.
