Figure 3-54, Using the Equation Editor to Generate Exponentially Decaying Sinewave
The last example as shown in Figure 3-26 is the most complex to be dis-
cussed 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 ex-
pression 1000*cos(110*omg*P) and the lower sideband by the term
1000*cos(90*omg*p).
Use the following equation:
Ampl(p)=5000*sin(100*omg*P)+1000*cos(110*omg*P)-1000*cos(90*omg*P)
Press [Preview]. Your screen should look like Figure 3-26.
