Fringe - 1-- Temporada Completa -Fringe — Temporada 1 es la temporada inaugural de la serie de ciencia ficción creada por J.J. Abrams, Alex Kurtzman y Roberto Orci. Emitida originalmente en 2008–2009, esta primera temporada establece el tono oscuro y enigmático de la serie, combinando investigación policial, experimentos científicos extremos y un trasfondo mitológico que crece episodio a episodio. The season’s true strength lies in its gradual reveal of the "Soft Spot"—the idea that the walls between our reality and a parallel universe are thinning. This culminates in a brilliant season finale that shifts the stakes from mere police work to an inter-dimensional conflict. The closing shot of the Twin Towers still standing in a parallel Manhattan remains one of the most iconic cliffhangers in television history. In retrospect, the first season of Fringe - 1-- Temporada Completa : A formerly institutionalized genius whose past work often holds the key to modern disasters.

| In synthesizer experiments you select the amplitudes and phases of the fundamental and 9 overtones to construct the beginning of a Fourier series. The sum is seen on a graphics display and the signal is available as sound card output. | ||||||||||||||||||||||||

You can test the Helmholtz assumption that the relative phases of the overtones are irrelevant to hearing. |

In analyser experiments you capture sound from the sound card or from a WAV file up to several seconds long, select the starting time of the time slice and analyse time and frequency responses. The example shows the spectrum of a piano playing a middle C (262 Hz). The non-harmonic overtones are clearly seen. (Due to the stiffness of the string, the frequencies of the partials are too high.) |

| You may filter data with a digital filter and display spectrograms in color mode. This example shows the spectrogram taken from the word "harris" in the frequency range 0..10 kHz with a 4096-point-FFT every 2 ms (post processing). The formants of "i" and the high spectral components of "s" are clearly visible. | ||||||||||||||||||||||||

| Short time spectral information may also be displayed in a 3-D representation, called "waterfall". The following example shows the waterfall spectrum of the same word "harris" as before. The red layer picks out the spectrum of "i" where the formants are visible again. The presentation may be rotated automatically or manually with scroll bars, in order to select the best "camera point". | ||||||||||||||||||||||||
