This allows the data to berepresented as the sum of a series of sines and cosines at variousamplitudes, rather than as a continuous function. Astronomers use Fourier transform to visualize the data as a … See more Another method that is useful for a signal with arbitrary shape isepoch folding. This is done by choosing a range of periods, and "folding"the data at those periods. As an example, say an astronomer has one reading per second … See more Fourier transforms are great at finding systems that have aconsistent periodicity, like pulsars. However, many sources of interesthave periodic … See more
