VIDEO EQUALIZER
■
GENERAL DESCRIPTION
NJM2258
is the IC functioning the gain high pass correction, as well as
for equalizing function of wave distortion correction, generated by bright
signal of group delay feature like low band filter. It has internalizing REC
line, one circuit, and then the playback line 2cirucuit.
