Salt-and-pepper noise, also known as impulse noise, is a form of noise sometimes seen on digital images. This noise can be caused by sharp and sudden disturbances in the image signal. It presents itself as sparsely occurring white and black pixels. An effective noise reduction method for this type of noise is a median filter or a morphological filter. For reducing either salt noise or pepper noise, but not both, a contraharmonic mean filter can be effective. (Wikipedia).

What Happens When You Put A Speaker In A Huge Vacuum Chamber? Can You Hear It?
Can you hear sound in space? In this video I put a speaker in my vacuum chamber along with a diaphragm with vibrating salt to see what happens when I suck all the air out of the vacuum chamber. The pressure waves vibrate the salt when there is air in the chamber, but once it is mostly gone

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

Frequency domain – tutorial 3: filtering (periodic signals)
In this video, we learn about filtering which enables us to manipulate the frequency content of a signal. A common filtering application is to preserve desired frequencies and reject the unwanted content. The learning objectives are to: 1) review the filtering concept using Fourier series
