1. Field of the Invention
The present invention relates generally to an audio signal device and more specifically it relates to an audio signal distortion detection device for simplifying the detection of harmonic distortion to aid in setting an amplifier's gain control to match an audio source unit's output voltage.
2. Description of the Related Art
Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.
The reduction of harmonic distortion is paramount to ensuring high quality audio through a speaker, amplifier and other sound-related devices. By reducing harmonic distortion, it can be assured that sound signals are being accurately reproduced with limited harmonics added by electronics or other outside sources.
In the past, the preferred method of adjusting an audio amplifier's input sensitivity control to reduce harmonic distortion was to use an oscilloscope. However, oscilloscopes often require a higher level of specialized training to ensure that the displayed waveform is properly interpreted by a technician. Thus, human error due to improper analysis of readings from an oscilloscope can result in a distorted reproduction of the audio signal. Other devices utilized for such functionality are generally not portable, expensive to purchase and difficult to read.
Because of the inherent problems with the related art, there is a need for a new and improved audio signal distortion detection device for simplifying the detection of harmonic distortion to aid in setting an amplifier's gain control to match an audio source unit's output voltage.
