Digital Theory

Word of the Day Analog How stuff works - How Analog and Digital Recording Works

Analog vs. Digital the arguments in a nutshell

Analog	Digital Good
Infinite dynamic quantization (infinite resolution)	Quantization error fix - more bit depth/oversampling
Good? - The warming effects 'we're used' to from tape compression.	Good?-'Perfect' reproduction of high frequencies - 'soundz harsh fix - 'using warm-sounding mikes and preamps (tubes)'
Bad - Tape noise and generation loss	Good - 'no generation loss'
Bad - 'Cheap recordings sound cheap'	Good - 'cheap recordings sound good but digital'

Binary Numbers

As Humans we use a 10 base numbering system. For machines this numbering system is impractical.

Gottfried Willheml von Leibnitz devised the binary number system in 1679

Converting Binary Numbers

Binary->Decimal

   110102 = (1 * 24) + (1 * 23) + (0 * 22) + (1 * 21) + (0 * 20) = 1610 + 810 +  0 + 210 + 0 = 2610

Dividing by two

integer	remainder	binary #
26
26/2	0	0
13/2	1	1 0
6/2	0	0 1 0
3/2	1	1 0 1 0
1/2	1	1 1 0 1 0
0/2		that's it kids

Base2

Each new bit doubles the number of intervals.

20	=1	monochrome, often black and white
21	=2
22	=4
23	=8	Most early color Unix workstations, VGA at low resolution, Super VGA, AGA http://en.wikipedia.org/wiki/Web_colors#Web-safe_colors
24	=16
25	=32
26	=64
27	=128
28	=256
29	=512
210	=1024

212	=4096
213	=8192
214	=16384
215	=32768
216	=65536	"thousands of colors" on Macintosh
220	=1048576
224	=16777216	Truecolor or "millions of colors" on Macintosh systems
232	= 4,294,967,295	refers to 24-bit color (Truecolor) with an additional 8 bits
264	= 18,446,744,073,709,551,616	= 16 exabytes. That's more than 18 billion billion bytes.
