Abstract
A signal separation apparatus applied in an image transmission system for extracting a chrominance signal from an analog composite video signal and a related method are disclosed. The signal separation apparatus includes an analog-to-digital converter for generating a digital composite video signal by sampling the analog composite video signal; a median filter, coupled to the analog to digital converter, for generating a reference luminance signal according to the digital composite video signal; and a subtractor, coupled to the analog to digital converter and the median filter, for generating the chrominance signal according to a difference between the digital composite video signal and the reference luminance signal.
