Number
DC restorer clamp time Back porch
Frequency response at 60 Hz Slow: 20% or less
Fast: 90% or greater
Attenuation of 60 Hz on input signal 12
Blanking level shift with 10% to 90%
APL change
APL changes from 50% to either 10%
or 90% will cause blanking level shift
of 1 IRE unit (7.14 mV) or less.
12
Blanking level shift due to presence or
absence of burst
1 IRE unit (7.14 mV) or less shift from
no color burst to presence of color
burst.
