In elektarooniga, kordhinta waa cabir ah awoodda wareegga laba-port (inta badan xoojiyaha) si loo kordhiyo awoodda ama amplitude ee signal ka soo galo si ay u soo baxaan dekedda by daray tamarta beddelay ka qaar ka mid ah korontada si ay calaamad. Waxaa sida caadiga ah waxaa lagu qeexaa sida saamiga celcelis ahaan ee amplitude signal ama awoodda at dekedda soo baxa si ay u ballaadhinta ama awoodda at dekedda soo gala. Waxaa inta badan lagu muujiyaa iyadoo la isticmaalayo logarithmic decibel (dB) unugyada ("dB kordhiyo").
"beta" waa saamiga istaatikada ee Ic oo loo qeybiyay Ib marka la joogo meel hawlgal ah.
