Is delta modulation digital or analog ?

Explanation

To determine whether delta modulation is digital or analog, we can analyze the characteristics and functioning of the technique step by step.

### Step-by-Step Solution:

1. **Understanding Delta Modulation**:
- Delta modulation is a method used to encode analog signals into a digital format. It works by sampling the analog signal and encoding the difference between the current sample and the previous sample.

**Hint**: Think about how delta modulation processes analog signals.
