摘要：
Recently malfunctions of telecommunication installations caused by switching noises of electric equipment or devices have been increasing. The switching noises usually have low frequencies between 2 kHz and 150 kHz. This paper shows some electric interference examples of telecommunication system cause by ac mains noises in frequency range from 2 kHz to 150 kHz. This paper also shows a necessity of emission requirements below 150 kHz for all equipment against EMC problems.
