Introduction
Music is a part of human culture, and the sound system is a
work of technology for realizing such a work, an outline of the
development of sound systems developed in the electronic and
mechanical sides unequal, especially in the tone of a series played
reschedule the low tones, with more small space to hear the low
tones blaring realize very difficult to realize with a small
loudspeaker size
Developing medical research comparable to the development of
electronics, the mathematical calculation can resolve the issue
thoroughly, without mechanically changing the size of the
loudspeaker, as the chain of a sound system that can not be
changed in size when used to generate a low tone
The mathematical approach is the most easily recognizable
picture in graphic form, because of its simplicity it is a physical
problem-solving approach can be expedited.
Methods
Comparison chart of operational device manufacturers
produced in the form of graphs published study, comparable to the
design are made equal in frequency and harmonic wave that has
been generated, or how to comparison chart between the device
under test and built.
In the world of medicine has studied human basilar ears when
he heard a low frequency which is manifested in the distribution of
nerves, significantly replaced by a small movement of the vibrating
hair in the ear canal, or called psychoacustic, in fact a form of
low-frequency vibrations can be replaced by a merger of the low-
frequency harmonic wave, in other words the so-called missing
fundamental
Results
The results of experimental measurements of the state actually
means missed by adjusting the power level, in the form of
comparisons in math based on missing fundamental power, and
synchronized power ratio in dB
Practical circuit Missing Fundamental
Conclusion
Math equation in the form of graphs can be used to reference the
real condition of the settlement based on the evidence of science
more complicated calculation in a practical embodiment of the circuit
Wave generator for the odd and even harmonics can be done by a
full-wave rectifier.
