FFT DEMO(圖1)-速報App

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:
