. introduction to the fourier transform virtually everything in the world can be described via a waveform - a function of time, space or some other variable. for instance, sound waves, electromagnetic fields, the elevation of a hill versus location, a plot of vswr versus frequency, the price of your
frequency component, we get the original waveform, shown in figure . figure . fourth fundamental frequency (left) and original waveform compared with the first four frequency components (overlapped). while this seems made up, it is true for all waveforms. this goes for tv signals, cell phone signals, the sound...
