Now lets try to modulate two sinewaves with different periods and
start phases. Type this:
Ampl(p)= 8000*sin(omg*p)*cos(omg*p*30)
Press [Preview]. Your screen should look like Figure 3-23.
Figure 3-52, Using the Equation Editor to Modulate Sine Waveforms.
In the example as shown in Figure 3-24, 20% second harmonic dis-
tortion has been added to a standard sinewave. The original wave-
form had a peak-to-peak value of 5000 points so 20% second har-
monic is equivalent to 1000 points. The frequency of the second
harmonic is obviously double that of the fundamental, so the term
+1000*sin (2*omg*P) is added to the original sine wave equation.
Use the following equation:
Ampl(p)=5000*sin(omg*P)+1000*sine(2*omg*P)
Press [Preview]. Your screen should look like Figure 3-24.
