pole roll-off frequency of about 500kHz. This suffi-

ciently attenuates the 3.58MHz (NTSC) or 4.43MHz

(PAL) color burst signal, yet passes the approximately

15kHz sync signals without appreciable attenuation. A

chroma filter will increase the propagation delay from

the composite input to the outputs.
