FFT DEMO

This app demonstrates the effect of change in FFT resolution both in time domain as well as frequency domain. The user can create a signal by mixing three sinusoidal sine waves with different frequencies and amplitudes. After selecting the value of N for the corresponding N-point FFT , the results can be examined graphically in frequency as well as time domains. Effect of aliasing effect can also be observed.Currently supports only 480 x 800 display resolution.Usage:1.Select the value of N2.Modify the sinusoidal signal parameters3.Click on COMPUTE button4. Click on GRAPHIC button ( Note: GRAPHIC button is enabled only after FFT computations are over)
