Signal processing

Noiselet

Noiselets are a family of functions which are related to wavelets, analogously to the way that the Fourier basis is related to a time-domain signal. In other words, if a signal is compact in the wavelet domain, then it will be spread out in the noiselet domain, and conversely. (Wikipedia).

What is Sound? - Quickly Discover What Sound Really Is

What is Sound? This simple demonstration visually shows how sound waves are produced from a vibrating surface. A frequency generator is hooked up to a power amplifier, and the resultant signal is used to drive a loudspeaker. The signal is also sent to an oscilloscope. After listen

Show Me Some Science! Speed Of Sound

Sound is a wave which travels through the air at about 330 m/s. The Little Shop of Physics Crew dances to the music together. When spread out along the track, it takes about a third of a second for the sound to travel from the first person to the last. The crew is blindfolded, so there are
