Amplitude ratio to dB conversion:
For amplitude of waves like voltage, current and sound pressure level:
GdB = 20 log10(A2 / A1)
A2 is the amplitude level.
A1 is the referenced amplitude level.
GdB is the amplitude ratio or gain in dB.
dB to amplitude ratio conversion:
A2 = A1 · 10(GdB / 20)
A2 is the amplitude level.
A1 is the referenced amplitude level.
GdB is the amplitude ratio or gain in dB.

What is amplitude ratio?
A measure of the strength of a wave is its amplitude which is the vertical distance between the heights of the wave's peaks and the heights of its troughs. An ocean wave might be said to be 20 metres high, for instance, meaning that an observer can see that the bottom of the wave is 20 metres below the top of the wave. The amplitude of that wave would be 20 metres. If you wanted to compare two waves you could use their amplitude ratio, simply the ratio of their two amplitudes.
How do you use a number line to determine the ratio?
You do not use a number line to find a ratio
How do you determine that the amplitude of y equals -2 sin x?
The amplitude of a function is half the distance between the maximum and minimum values. This is the absolute value of the number in front of the trig function. for example, y=Asin(x) or y= Acos(x) the absolute value of A is the amplitude. Therefore, the amplitude of y=-2sinx is 2
Determine the amplitude of y equals cos x?
The amplitude is ' 1 ' .
What does amplitude determine in light?
Amplitude of light waves determines the brightness or intensity of light. A larger amplitude corresponds to a brighter light, while a smaller amplitude indicates dimmer light.
Does the amount of energy determine its amplitude?
No, the amount of energy does not determine the amplitude of a wave. Amplitude is a measure of the maximum displacement of a wave from its equilibrium position. Energy is related to the intensity of the wave, which is determined by the square of the amplitude.
Determine the amplitude of y-2 sin x?
The amplitude is |-2| = 2.
Determine the amplitude of y equals -4 sin x?
The amplitude is 4 .
What is modulated depth?
In amplitude modulation, modulation depth refers to the ratio of the unmodulated carrier amplitude to the amplitude deviation for which the modulated carrier wave reaches its minimum value. If this minimum value is zero, the modulation depth is 100%.For amplitude modulation,modulation depth = (a-b)/(a+b),wherea is the unmodulated carrier amplitude, andb is the minimum amplitude deviation.The modulation depth ratio is also referred to as the modulation index.
What is depth of modulation?
In amplitude modulation, modulation depth refers to the ratio of the unmodulated carrier amplitude to the amplitude deviation for which the modulated carrier wave reaches its minimum value. If this minimum value is zero, the modulation depth is 100%.For amplitude modulation,modulation depth = (a-b)/(a+b),wherea is the unmodulated carrier amplitude, andb is the minimum amplitude deviation.The modulation depth ratio is also referred to as the modulation index.
What does the amplitude of a sound wave determine?
Amplitude is the energy of a sound wave, which we also call Loudness
What factors determine the amplitude of axon potential in neurons?
The factors that determine the amplitude of axon potential in neurons include the strength of the stimulus, the size of the axon, and the presence of myelin sheath.

What does the amplitude of a wave tell about a sound?
The amplitude of a wave determines the loudness of a sound. A larger amplitude indicates a louder sound, while a smaller amplitude corresponds to a quieter sound.
Determine the amplitude of y equals -2 sin x?
The amplitude of the wave [ y = -2 sin(x) ] is 2.
