Abstract :
Digital television requires several building blocks to perform the total video signal processing digitally. One of them is a chroma filter, which has to separate the colour information from the brightness information (luminance). In this paper two 17.7 MHz digital low-pass filters are discussed, which perform-in combination with other circuitry-the above mentioned function. Both filter functions are implemented in a dual mode chip made in 4/um NMOS E/D technology with implanted undercrossings.
