That all makes sense, except for one part. If the color generator receives a ~42.95 MHz clock, doesn't that only allow for 8 samples of the signal at the sub-carrier frequency? If so, how does one align the sub-carrier at 12 different phase offsets with only 8 samples to "wiggle" in? Wouldn't this cause some level of aliasing?The color generator is clocked by the rising and falling edges of the ~21.48 MHz clock, resulting in an effective ~42.95 MHz clock rate. There are 12 color square waves, spaced at regular phases. Each runs at the ~3.58 MHz colorburst rate
If I've grossly misunderstood this, please enlighten me.
