Abstract :
This paper proposes a novel 7-tap sin(x)/x correction digital filter suitable for DVB-C/DAVIC modulator, which can compensate the sinc effect of D/A converter. This filter adopts the modified direct form structure, which has high performance as well as smaller chip area. In addition, it adopts an efficient BIST (built in self test) scheme to greatly improve the testability
