**1. The problem statement, all variables and given/known data**

In comparison with the sampling sine wave, in order to reconstruct a square wave, do we need to increase or decrease sampling frequency?

**2. Relevant equations**

Aliasing effect

Leakage effect

**3. The attempt at a solution**

No matter square wave or sine wave, the experimental results shown the higher sampling frequency (10kHz, 25kHz, 100kHz, 250kHz, 2.5MHz) construct a clearer waveform (signal freq = 25kHz).

Is there difference between sine and square wave for "increase or decrease sampling frequency"?

Thank you
