WebAt high frequencies, it is often useful to show the individual distortion components separately rather than specifying THD. The AD9620 is a 600-MHz (typical -3-dB bandwidth) low distortion unity-gain buffer. Here are graphs of the AD9620’s second and third harmonic distortion as a function of frequency for various loading conditions. Q. WebDetails. Total harmonic distortion (THD) is a function versus frequency that helps quantify how well the output of a system replicates the input. The lower the THD values, the less the noise or distortion in the system output. THD measurements are used in many applications by different industries. This article concentrates on the use of THD in ...

WebTraditional harmonic distortion measurements only exploit the amplitude of the harmonic components. The phase of the higher-order harmonics is usually neglected because the interpretation is difficult. However, both phase and amplitude spectrums determine the waveform of the distortion in the time domain [34]. The waveform of the harmonic ...
