[edit] Summary

This figure represents a rectangular waveform used to define the concept of dutycycle. It has been generated using the following gnuplot code (executed by gnuplot 4.0):
# This file is used to generate a plot that defines the
# concept of duty cycle
# graph configuration
set terminal postscript eps enhanced "Times-Roman" 18 color solid
set encoding iso_8859_15
set size 1,0.5
unset title
set line style 1 lt 3 lw 3 pt 0 ps 0
set border 15 lt 7 lw 4
set grid xtics ytics
set ylabel "Amplitude"
set xlabel "Time"
set samples 1000
# equation of the signal
dutycycle=0.333333
signal(x) = x-floor(x)>dutycycle?0:1
set xtics ("0" 0,"{/Symbol t}" dutycycle,\
"T" 1, "T+{/Symbol t}" 1+dutycycle,\
"2T" 2, "2T+{/Symbol t}" 2+dutycycle,\
"3T" 3, "3T+{/Symbol t}" 3+dutycycle)
set ytics ("0" 0, "1" 1)
set output "dutycycle.eps"
plot [0:3.5][-0.25:1.25] signal(x) ls 1 title ''
And the eps file has been converted into png using the following command (linux)
convert -density 300 dutycycle.eps dutycycle.png
