Analog and Digital

• Analog
• Continuous, Waves, Comparison
• Process- Amplify/Dampen Wave
• Examples- sound waves to records
• [extended: meaning, metaphor]
  
• Digital
• Discrete, Sampling, Juxtaposition
• Process- logical encoding/decoding samples into code
• Examples- sample waves into binary code, CD's
• [extended: words, alphabet as codes; metonym/juxtapose]
  
• Sampling
• Frequency- how often ("grain"); or under what condition
• Range- how long or how large ("extent")
• Code- into what new language
• [devices- sampler/ recorder/ computer/ player]
  
• Manipulation of the code
• Error Correction- Was the sample/transmission good?
• Noise Reduction- adding filters
• Altering and Mixing- Re-organizing patterns
