Spectrum Windows
Nowhere in the world will you find such climatic variations: desert in the west, alpine tundra and glaciers in the north, humid tropical regions supporting rainforests in the southwest. Temperatures rise to a severe as 50° C in the desert and fall to sub-zero in the Himalyas. Onslaughts of ultra violet rays, tropical heat, monsoon storms, ferocious coastal winds and 95% humidity make India unique. In these conditions, only thoese windows with special qualities can serve and survive. Most immediately, it provides an array of useful window types which are best for different situations. Second, by studying windows and their Fourier transforms, we build up our knowledge of Fourier dualities in general. Finally, the defining criteria for different window types often involve interesting and useful analytical techniques.
