Figure 3-36, Using the Equation Editor to Generate Exponentially Decaying Sinewave
The last example as shown in Figure 3-37 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*p) and
the lower sideband by the term 100*cos(90*omg*p).
Use the following equation:
Ampl(p)=6000*sin(100*omg*p)+1200*cos(110*omg*p)-1200*cos(90*omg*p)
Press [Preview]. Your screen should look like Figure 3-37.
