Electronics is fundamental to modern life. Take for example this free course, Electronic applications. An interactive website with videos and interactive software will show how electronic systems pervade everything we do; review some basic ideasof signal processing, control and communications; and allow you to use a digital filter to remove Gaussian noise from a signal.  Transcript
