| Abstract: | Refference signal has relation to useful signal, but no relation to noise signal. Based on this principle, relevant detection technique is a weak signal examination technique which can reduce the noise signal through relevant operation and can increase the signal-noise ratio relevant detection technique is the best technique among various weak signal examining techniques which can perform the largest signal-noise ratio and can recover the oniginal signal. |
