Examples of systems are TWACS and Turtle (TS1 and TS2). 5kHz) when using DB8PSK modulation. Because power-lines carry 60 Hz ac, the voltage on them passes through two peaks each cycle (one positive and one negative) and pass through zero twice each cycle. The law NB-PLC standards define communication protocols operating below 500 kHz frequency with a bandwidth from tens to hundreds of kbps. The performance of PLC degrades due to the presence of different types of noise interferences generated by electrical appliances. This paper focuses on certain techniques for denoising of such non stationary ECG signal.
