| The detection on the speech signals is to solve the problem in various complex environments of noise and interference, which the effective detection on the speech signals can't be conducted. If the auto- detection on multiple speech signals is realized, the auto-switch and record of multiple speech signals can be done. In practice, it can be extensively applied in military, civil aviation, transportation, and the national security. According to this principal, an electromagnetic analyzer base is set up, and compare and identify automatically the received electromagnetic signals, complete the detection on the electromagnetic signals. |
