Abstract

Bulus uygulanan giris sinyaline cevaben dogrusal olmayan özel bir sinyal veren bir birinci kuvvetlendiriciyi dogrusallastirmak için yöntem ve aygita iliskin olup, sunlari içerir: ikinci bir kuvvetlendirici, sinyal kaynagindan alinan giris sinyalinin birinci kismini ikinci kuvvetlendiriciye uygularak çikis sinyali alabilen vasitalar; giris sinyalinin ikinci kismiyla çikis sinyali arasinda fark olup olmadigini saptayarak fark sinyali veren vasitalar ve düzeltilmis çikis sinyali almak üzere düzeltilmis giris sinyalini birinci kuvvetlendiriciye uygulayan vasitalar; özelligi sunlari içermesidir: ters fark sinyali elde etmek için fark sinyalinin fazini ters çeviren vasitalar, ve düzeltilmis giris sinyali elde etmek için bu ters fark sinyaliyle giris sinyalinin ikinci kismini birlestiren vasitalar.
