We can derive frequency spectrum from the result of making a calculation of the Black Burst Signal. Frequency spectrum having a f_H (15.734KHz) pitch and f_f(60Hz) pitch in interlieving of chrominance with luminance components are shown graphically. From these graphs, we may know the meaning of FUKINUKI HOLE in one-dimensional spectrum. Comparing the graphs with observations of a high resolution spectrum analyzer, we are confident of an effectiveness of our calculation method of frequency spectrum analysis on Black Burst Signal. Any arbitrary frequency can be applied to this calculation method to get a fine structure of spectrum because the method is based on the computer simulation manuver.
