Analysis of Color Transient Response in the NTSC System

The composite color transient response in a television system is a complex function influenced significantly by widely different luminance and chrominance band-widths, wide-band transmission of one modulated chroma subcarrier (I) and narrow-band transmission of the other (Q), luminance-chrominance delay matching, non-linear pick-up and display characteristics, chromaticities of the pick-up and display primaries and white illuminants, etc. This is in addition to any distortions introduced by the receiver circuits, such as the chroma bandpass filters, demodulator low-pass filters, etc.
