| () |
| Abstract: |
| A method to evaluate errors of time interleaved ADC systems is introduced, the spectrum is analyzed, and the principle of evaluating time errors of un - equalized sample ADC systems is described. Simulation results show that the method can greatly improve the performance of high - speed sample systems. |
| Key words: reconnaissance system data acquisition time - interleaved parallel sample un - equalized sample time delay evaluation |
