Are there any advantages oversampling?
Nyqusit Frequency simply means &quot;half the sample rate&quot;
Undersampling means your signal bandwidth is higher than the Nyquist Frequency. You get aliasing
Oversampling means your signal bandwidth is lower than the Nyquist Frequency. You don't get aliasing
Most practical applications choose a Nyquist Frequency that's slightly higher than the highest frequency of interest. That gives some space to manage the transition band between the signal frequencies and the Nyqusit Frequency (at which the signal should be 0). For example audio is considered to have 20 kHz bandwidth but the typical Nyquist frequencies are 22.05 kHz or 24 kHz
