Total harmonic distortion (THD) is defined as the ratio of the rms voltage of the harmonics to that of the fundamental component. This is accomplished by using a spectrum analyzer to obtain the level of each harmonic and performing an rms summation.

Calculate Total Harmonic Distortion (THD) using our online calculator. Learn the THD formula and convert between THD (%) and THD (dB).

Nov 29, 2022 · Distortion measurements (THD, THD+N and IMD) are traditionally expressed in terms of percent. But what do 1%, 0.1%, 0.01% or 0.001% mean in terms of loudness or audibility?

The total harmonic distortion calculator is a tool that converts signal distortion from percent to decibel value and vice versa.

This Total Harmonic Distortion (THD) calculator determines the distortion factor THD as a percentage from known distortion attenuation in decibels and vice versa. Example: Calculate the THD factor of an operational amplifier as a percentage if its THD attenuation is –60 dB.

The total harmonic distortion (THD or THDi) is a measurement of the harmonic distortion present in a signal and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency.

Nov 15, 2017 · Distortion measurements (THD, THD+N and IMD) are traditionally expressed in terms of percent. But what do 1%, 0.1%, 0.01% or 0.001% mean in terms of loudness or audibility?

This is a Total Harmonic Distortion (THD) Calculator tool that can be used alongside your Oscilloscope FFT or spectrum analyzer to find out the total harmonic distortion of your signal.

Nov 22, 2023 · Total harmonic distortion plus noise (THD+N) is a common metric in audio interface specifications. It measures the unintended harmonics and noise in an output signal relative to an input signal. Audio interface THD+N specifications are often quoted as either percentages (%) or ratios (dB).

The level of the output voltage level is 0 dB, that is 100% (factor or ratio = 1). The level of −3 dB is equivalent to 70.7% (factor = 0.7071), and the level of −6 dB is equivalent to 50% (factor = 1/2 = 0.5) of the initial voltage. This applies to the field quantity voltage or sound pressure.
