[edit] Summary

An example of 4-bit pulse code modulation showing quantization and sampling of a signal (red).

Generated by myself using Inkscape to heavily modify gnuplot output.

Lissajous small.svg
 This vector image was created with gnuplot.

[edit] Details

Generated curve and scale with the following gnuplot script:

set terminal svg size 1600 1200 fname "Times New Roman" fsize 48 enhanced
set output "pcm.svg"
set samples 1000

set nokey
set grid ytics lw 4
set xtics 32
set mxtics 32
set ytics 1
set noxzeroaxis
set noyzeroaxis
set noborder

set xrange [0:32]
set yrange [0:15]

plot 7.5*sin(2*pi*x/32) + 7.5 lw 4

Floor function was then performed by hand in Inkscape, along with various other image quality tweaks.
