FFT Explorer

FFT Explorer will let you interactively produce 2 independent waves, sin, triangle, or square from 1 to 60 cycles as well as their phase from 0 to 2pi. The FFT of the composite of both waves is displayed. There are 4 graphs shown Wave A, Wave B, the composite sum of A and B and the FFT of the composite. There are 4 wave controls , A cycles and phase, and B cycles and phase, along with controls for choosing wave types. All graphs are interactive and are shown immediately as the user changes parameters.
