Db/decade meaning

> A DECADE is an interval between 2 frequencies with a ratio of 10 (between 10 Hz and 100 Hz or between 500 Hz and 5000 Hz). > 20 dB/decade means that magnitude changes 20 dB whenever the frequency changes tenfold or one decade. > Slopes are expressed in dB/decade.

How many decibels is a decade?

However, in other fields within electronics, we describe the slope per decade, like 20 dB per decade. An octave is defined as a doubling or a halving of a value of frequency. A decade is defined ten times (or a tenth of) any quantity (or frequency range); this means the values are not fixed, but relative.

How to convert dB decade to dB octave?

How to convert decibel/decade to decibel/octave ? 10dB/decade = approx. 3dB/octave.

What is a decade in a Bode plot?

Every tickmark on the frequency axis represents a power of 10 times the previous value. For instance, on a standard Bode plot, the values of the markers go from (0.1, 1, 10, 100, 1000, ...) Because each tickmark is a power of 10, they are referred to as a decade.

What does dB per octave mean?

They're usually defined in terms of decibels per octave. For example, the 24 decibel per octave slope on a filter means that when you get one octave higher than the cutoff frequency, those harmonics have been reduced in strength by 24 decibels, or 24 dB.
