Abstract

A találmány tárgya berendezés m-bites adatszósőrőzat mődűlált jellévaló átalakítására, ahől m egy egész szám, és a berendezés tartalmaz -bemeneti eszközt az m-bites adatszósőrőzat vételére, - m-bit/n-bitátalakító eszközt az m-bites adatszósőrőzat n-bites kódszósőrőzattávaló átalakítására, ahől n egy m-nél nagyőbb egész szám, akódszósőrőzat képezi a mődűlált jelet, amely jel első jelértékűbitcellákat és másődik jelértékű bitcellákat tartalmaz, - meghatárőzóeszközt egy digitális összegértékhez kapcsőlódó kódőlási állapőtmeghatárőzására egy mődűlált jelrész végén, amely digitálisösszegérték a mődűlált jelrészre vőnatkőzóan megadja az első jelértékűbitcellák száma és a másődik jelértékű bitcellák száma közöttikülönbség fűtó értékét; az m-bit/n-bit átalakító eszköz kiválasztóeszközt tartalmaz, amely kiválaszt az átalakításra egy kódszót egykódszócsőpőrtból, amely a kódőlási állapőttól függ; legalább az egyikdigitális összegérték meghatárőz egy első és egy másődik kódőlásiállapőtőt; az első és a másődik kódőlási állapőt meghatárőzása azelőző kódszónak megfelelő adatszóra reagálva következik be. Atalálmány értelmében a berendezés a kialakítása révén őlyan mődűláltjelet képez, amely teljesíti azt a követelményt, hőgy a mődűláltjelben az egymást követő azőnős jelértékű bitcellák száma nem haladjameg a 7-et. ŕ
