It is well known that the frequency of the HPF and the capacitance of the component within are inversely proportional to one another. However, when the pathological test (PLL) is used for both HD and SD video, results show that the lowest acceptable capacitance value of the HD filter is greater then that of the SD filter. These seems to contradict the very basic first principles of HPF's, since the frequency of HD is much greater then that of SD.
Any help greatly appreciated. Thanks
Aside: a PLL test simply takes long strings of 1's and 0's instead of having it alternate every bit, effective reducing the frequency, by a factor of 20 for both.
