RECONSTRUCTION FILTER FL390 This tightly specified filter provides close tolerance amplitude and group delay response together with Sinx/x correction over an extended bandwidth for reconstructing video signals to be converted at 30 MHz. High attenuation levels are achieved at ½ S.F. and 4 x fsc (NTSC + PAL) together with good stopband performance making the filter ideal in allowing high quality analogue outputs from a multistandard digital test pattern generator. The filters are also supplied in matched delay sets to provide close timing of individual component channels.
