Figure 3-57. Using the Equation Editor to Generate Exponentially
Decaying Sinewave
The last example as shown in Figure 3-25 is the most complex to be
discussed here. Here, 100 cycles of sinewave are amplitude
modulated with 10 cycles of sine wave with a modulation depth of
20%. To achieve this, the upper and lower sidebands are defined
separately and added to the fundamental or carrier. The upper
sideband is produced by the expression 100*cos(110*omg*t) and the
lower sideband by the term 100*cos(90*omg*t).
Use the following equation:
Ampl(p)=5000*sin(100*omg*t)+1000*cos(110*omg*t)-1000*cos(90*omg*t)
Press [Preview]. Your screen should look like Figure 3-28.
