In the recently decades, with the development of the DSP technology, predistorting technique is realized with digital mode, due to baseband signal is easily dispose and temperature and aging, variations of operating point etc.

- 隨著(zhù)數字信號處理(DSP)技術(shù)的發(fā)展,最近十多年來(lái),人們都用數字方式來(lái)實(shí)現預失真技術(shù),鑒于基帶信號容易處理且能隨溫度變化、電源電壓波動(dòng)、發(fā)射管老化等環(huán)境變化做到自適應調節,因此,目前的預失真器基本上都是采用數字方式。
