b roadcast fm r adio r eceiver CL6017S 10 the CL6017S integrated stereo decoder automatically decodes the mpx signal using dsp techniques. the 0 to 15 khz (l + r) signal is the mono output of the fm tuner. stereo is generated from the (l + r), (l - r), and a 19 khz pilot tone. the pilot tone is used as a reference to recover the (l - r) signal. output left and right channels are obtained by adding and subtracting the (l + r) and (l - r) signals respectively. 4.3 audio processing pre-emphasis and de-emphasis is a technique used by fm broadcasters to improve the signal-to- noise ratio of fm receivers by reducing the effects of high frequency interference and noise. when the fm signal is transmitted, a pre-emphasis filter is applied to accentuate the high audio frequencies. all fm receivers incorporate a de-emphasis filter which attenuates high frequencies to restore a flat frequency response. two time constants are used in various regions. the de-emphasis time constant is programmable to 50 or 75 s with the de bit. the CL6017S de-emphasis filter and compensation effect is shown in below figure. 0 5000 10000 15000 -20 -15 -10 -5 0 5 frequency[hz] amplitude[db] de-emphasis filter 75us 50us 0 5000 10000 15000 -0.2 -0.1 0 0.1 0.2 de-emphasis error frequency[hz] amplitude[db] 75us 50us figure 4. de-emphasis filter CL6017S has a bass boost filter to enhance low frequency. chipkingdom electronics tel:86-755-8361-4001 fax:86-755-8325-6596 www.chipkingdom.com www.datasheet.co.kr datasheet pdf - http://www..net/
