How much carbon dioxide per mile is produced by the average gasoline car vs. a coal-powered electric car? I'm looking for overall carbon footprint based on pollution at the power plant and pollution by the car.
A harmonic interval results if the notes are played at the same time, whereas a melodic interval occurs when the notes are successively. If they are playing more than one note at a time then it is harmonic or has harmony. If they are playing one note at a time then its melodic or a melody.
From Wikipedia, the free encyclopedia. The total harmonic distortion, or THD, of a signal is a measurement of the harmonic distortion present and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency.HD+N means total harmonic distortion plus noise. This measurement is much more common and more comparable between devices. It is usually measured by inputting a sine wave, notch filtering the output, and comparing the ratio between the output signal with and without the sine wave:
