What is logarithmic decrement?
A measure of the mechanical damping. The logarithmic decrement is measured dynamically using a torsion pendulum, vibrating reed, or some other free vibration instrument, and is calculated from the natural logarithm of the ratio of the amplitudes of any two oscillations. Its formulation is: whereAi = amplitude of the ith oscillationA(i+n) = amplitude of the oscillation n vibrations after the ith oscillation.
What is the decibel a unit of?
Decibel is no real unit, it is a pseudo unit. The decibel (dB) is a logarithmic unit that indicates the ratio of a physical quantity. A change in voltage ratio by a factor of two is approximately a 6 dB change. A change in power ratio by a factor of two is approximately a 3dB change.
What are logarithmic numbers?
Exponents
How would you explain logarithmic converter?
Logarithmic functions are converted to become exponential functions because both are inverses of one another.
What is the logarithmic equation of finding the relationship between two variables?
A basic logarithmic equation would be of the form y = a + b*ln(x)
