Abstract	This paper investigates the effects of EFT/burst on ADSL noise spectral background. The conducted immunity EFT/burst test is a very severe test in EMC test family. The test signal is a very fast transient and has significant energy level. It is worth noting that because of their repetitive nature, EFT/burst events can also result in erratic behavior of a communication system. This paper is written with the aim of verifying experimentally the effects of EFT/burst signal on the ADSL 25 kHz to 2.2 MHz. Based on our early finding; it was found that the EFT/burst can increase the background noise power spectrum density within ADSL spectrum by 19 dB in average. This phenomenon definitely will reduce the signal to noise ratio (SNR) of the ADSL system, which will significantly jeopardize the ADSL performance and causing unreliable connectivity.
