In this section, we constructed VI with front panel to test the effect of aliasing under the rule of Nyquist frequency. The programming included 2 graphs which are waveform chart in term of time domain and waveform graph in term of frequency domain. These 2 graphs are for displaying the behavior of frequency when it’s varied. The frequency started from 10 Hz to 10 KHz. Then, we had varied the frequency and the frequency after 5000 Hz the power spectrum of frequency in the graph was changed and distorted from the real frequency input. This is because of the sampling rate is less than haft of frequency rate which violated Nyquist rules.
