Electrical Noise
Electrical noise is a high-frequency interference in the frequency spectrum of 7000 Hz to over 50 MHz. Noise can be transmitted and picked up by a power cord acting as an antenna, or it can be carried

Noise Distribution
Noise is generally distributed across the frequency spectrum. Many common noise sources produce a white noise distribution; this means that the spectral noise density is the same at all frequencies.
