The first topic of the thesis presents an NTSC digital video decoder which is designed by using two lines delay comb filter to decode the luminance signal (Y) and the chrominance signal (C). The coefficients of the low pass filter are tuned properly to reduce the gate count without losing any original performance of the chroma demodulator.
The second topic of the thesis is to propose a method and a circuitry to resolve the out-of-phase problem between the color burst and the sub-carrier in NTSC TV
receivers. The feature of the method is that a delay means is inserted which leads to
the synchronization of the color burst and the sub-carrier such that the following
color demodulator is able to extract right color signals. Besides, the locking of the
two signals will be fastened without any extra large circuit cost.
