| Abstract: | A new control and reversion technique of transfer function is put forward,which is implemented by first test-ing accurate amplitude/phase-frequency curves during the process of data acquisition in real time,and are based on software with the YSL know-how.This method is applied successfully in the DASP software.The theoretical foundation and formulas,the schematic diagram of the transfer function measurement and reversion technique,the testing data and its analysis are given,this provides optimal transfer function in real time,extends the frequency range,and gets more accurate measurements. |
