## How to Determine Sampling Rate
The Nyquist theorem states the minimum sampling rate is twice the highest signal frequency.
### Formulas
**f_sample_min = 2 x f_max**
**f_sample_practical = Oversampling Ratio x f_max**
In practice, engineers oversample (4x to 8x or more) because:
- Perfect brick-wall anti-aliasing filters do not exist
- Oversampling reduces quantization noise
- It allows simpler, cheaper analog filters

Ejemplo Resuelto
Capture audio up to 20 kHz with 2x oversampling.
- Minimum (Nyquist): 2 x 20,000 = 40,000 Hz
- Practical rate: 2 x 20,000 = 40,000 Hz
- Data rate (16-bit): 40,000 x 16 = 640,000 bits/s = 640 kbps
