How do you find the fundamental frequency of a function?
If the frequencies are all integers and exact multiples of a fundamental frequency, you can simply take the greatest common divisor of the frequencies. If you're told the frequencies are 1760, 2200, and 3080, then the fundamental frequency is apparently 440 since that's the greatest common divisor.
What is fundamental frequency?
The fundamental frequency, often referred to simply as the fundamental, is defined as the lowest frequency of a periodic waveform. In music, the fundamental is the musical pitch of a note that is perceived as the lowest partial present.
