How do you find amplitude from dB?

Decibels are a relative unit, they express the power of your signal relative to some reference power. If you are working with amplitudes, then the formula is: power_db = 20 * log10(amp / amp_ref); (See http://en.wikipedia.org/wiki/Decibel#Field_quantities).

How do you convert dB to magnitude?

The relationship between magnitude and decibels is ydb = 20 log₁₀( y ).

Is amplitude the same as dB?

Amplitude, reported on the decibel (dB) scale, measures sound's pressure or forcefulness. The more amplitude a sound has, the louder it is. In daily life, we often think of this as volume.

How to convert dB to Hz?

Decibel is a unit of intensity and hertz is a unit of frequency, no direct conversion exists between them.
