... Philips Semiconductors Integrated NTSC comb filter FUNCTIONAL DESCRIPTION Functional requirements The NTSC comb filter processes the video standard NTSC M. For SVHS signals the input signals are bypassed to the output without processing by selecting the SVHS mode. A sync separation circuit is incorporated to generate control signals for the internal clock processing. With a sync compression (see Fig ...

... Philips Semiconductors Integrated NTSC comb filter SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities ...
