= 3.579545 MHz for the NTSC M system.
With respect to 227.5 colour subcarrier periods (equals 63.556
μ
s) due to 1H delay in the comb filter.
With respect to the voltage level during clamping.
Test signal for NTSC M: 100% amplitude FCC multi-burst (see Fig.4).
Test signal for NTSC M: 100% white 75% amplitude FCC colour bar.
