# 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 out by a vocal synthesiser) is in Japanese.  

## Simple notes  
 
For things that are not easily pronounced (e.g. formulae, expressions, symbols), inclusive either:  
- Mark how the thing should be pronounced in a pair of adjacent parentheses  
  - e.g. H(ω) (エッチオメガ)  
- (inclusive) Or don't embed these elements too deep into the flow of sentences; use common, laymen's language instead  
  - e.g. not `Fs/2（サンプリング周波数の半分）までの帯域を忠実に再構成できる` but `サンプリング周波数の半分までの帯域を忠実に再構成できる`

The general direction is to stay boring, but the deadpan kind of boring. Keep technical language appearing but explain things in more laymen's language.
