Principle of the intersective pulse width modulation (PWM).

 
This plot was created with Gnuplot by n.

The list of points used to define the tics along the x axis has been generated by the following python code:

#!/usr/bin/python

#this file generates a list of points used as ticks
# to draw the grid in the gnuplot file pwm.plt
from scipy import *

freq= 0.05

n=20
for i in range(n):  
    def f(x):
        return sin(freq*x*2*pi)-2*x+1+2*i
    print i,",", optimize.fsolve(f,0), ",\"
