# digital signal processing 

A boring lecture about signals and systems, and its digital implementation in DSP.  
Borderline 'song' less 'poetic'.  

The actual material (text that is read) is in Japanese.  

## Outline
### Signals and Systems
- Linear time-invariant systems (and nonlinearity)
- Signal transformations
- Impulse signal
- ...

### Digital Signal Systems
- The impossibility of real continuous signals in digital systems
- Discrete time
- ...
