The three key steps involved in analog to digital conversion are:
1. **Sampling** - This is the process of measuring the amplitude of the analog signal at discrete intervals of time.
2. **Quantization** - This involves mapping the sampled values to a finite set of levels, effectively rounding the sampled values to the nearest defined level.
3. **Encoding** - This step converts the quantized values into a digital format, typically using binary representation.
**Hexadecimal conversion** is not a key step in the standard analog-to-digital conversion process but may be used in representing the digital output.
So, the correct answers are:
- **quantization**
- **encoding**
- **sampling**
