Abstract :
The implementation of an adaptable suppresser of single interference using a FPGA-type (Xilinx) logic programmable device/mechanism is shown in this article. The adaptable suppresser adjusts its parameters automatically to eliminate noise. This ability allows the suppresser to adapt to the changes in the characteristics of the signal. The use of this adaptable suppresser to filter the interference caused by the power line is shown
