This tool converts deciBel Hertz (dB-Hz) to Hertz (Hz).
Background
deciBel or dB represents a ratio of two numbers – typically Amplitude or Power Levels. The units are the same and hence dB is simply a ratio.
Hz is a unit of frequency and is equivalent to cycles per second.
dB-Hz or dB (Hz) is the bandwidth relative to 1 Hz
A linear number can be converted to its dB equivalent using this calculator. the formula is Plinear = 10(PdB/10)
Similarly,
Hz = 10(dB-Hz)/10
dB has a logarithmic nature. The beLinearnefit of using dB is that a very large (or very small) ratio can be conveniently represented by a small number. For example, 10000000000 Hz = 100 dB-Hz.
Example Calculations
20 dB-Hz is equivalent to 100 Hz.
Similarly 30 dB-Hz is equivalent to 1000 Hz.
