Description: A monochrome diagram displaying multiple Phon curves with labeled decibel sound pressure levels (dB SPL) on the y-axis and frequency in Hertz (Hz) on the x-axis. The graph features a barred frequency response with various curved lines representing different phon levels, such as 120, 960, 180, 900, and several instances of 'Phon'.
Description: A black background features a yellow triangular caution symbol with a black outline. Inside the triangle is a black wave-like line representing a frequency. Below the symbol, in bold white sans-serif text, reads 'WARNING: ANALYZING YOUR FREQUENCIES.'

Description: In 1822, Joseph Fourier showed that some functions could be written as an infinite sum of harmonics. This method called fourier series allowed us to construct very complex signal by only using the summation of sine and cosine signal. Furthermore by taking some statistic method, the scientist figure out that this complex signal can be transformed into frequency domain, so the analyzing or utilization of signal was becoming more advance. Nowadays application of fourier transform can be found everywhere. Your smartphone, your face recognition, radio, stock exchange, heart monitor, etc. And finally it is time to found its application in your daily outfit. Grab it fast.
