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: Rendered on a deep dark background, this artwork presents four sine harmonics stacked above a square wave rebuilt from their sum, with the series f(x) = 4/π Σ sin(nx)/n for n = 1, 3, 5, 7. In 1822 Joseph Fourier showed that any periodic signal can be written as a sum of sines and cosines. Fourier analysis now underpins audio, image compression, telecommunications and much of modern engineering. Made for engineers, inventors and anyone who loves to understand how things work, it suits a workshop, office or study.

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.
