FL952 OVERSAMPLING FILTER The Faraday FL952 is a reconstruction filter for use in oversampled systems using the Raytheon 22191/22091 and 22193 digital video encoder. It combines removal of clock frequency and sidebands in conjunction with the Raytheon digital filter, sinx/x correction and also pre-distortion of the amplitude response to compensate the roll off / ripple of the lower tap digital filter employed by the Raytheon. • Low cost oversampled reconstruction filter. • Excellent repeatability between filters. • Digital filter roll off compensation.. • Space saving SIL format. • Sinx/x correction.
