Noise Density in Analog Communications Formulas

Noise density is the power spectral density of noise or the noise power per unit of bandwidth. And is denoted by N₀. Noise Density is usually measured using the Watt-Second for Energy. Note that the value of Noise Density is always positive.

FAQ

What is the Noise Density?

Noise density is the power spectral density of noise or the noise power per unit of bandwidth. Noise Density is usually measured using the Watt-Second for Energy. Note that the value of Noise Density is always positive.

Can the Noise Density be negative?

No, the Noise Density, measured in Energy cannot be negative.

What unit is used to measure Noise Density?

Noise Density is usually measured using the Watt-Second[W*s] for Energy. Joule[W*s], Kilojoule[W*s], Gigajoule[W*s] are the few other units in which Noise Density can be measured.
