| Abstract: | Electric Erasable Pot(E 2POT) nonvolatile digital potentiometer is a new device developed in recent years. It can keep its present status and its value can be changed by digital method. This paper presents an introduction how to make a numerical control attenuator capable of being located accurately and keeping the status of demand using four X9314 potentiometers. It can present the indication of decrement. |
