Abstract :
A method based on simple interpolation and correlation techniques is described for the estimation of some of the nominal characteristics and temporal variations of a digital magnetic recording channel for video recording. These estimates include the linear and nonlinear channel responses, timing jitter, and amplitude and bandwidth variations along a track in normal and fast forward modes of operation. The same technique can also be applied to examine transient channel variations around the time of dropouts. These estimates may be useful for the design of a phase-locked loop and an adaptive equalizer for a digital video tape recorder
