In the following example, as shown in Figure 5-23, 20% second
harmonic distortion has been added to a standard sinewave. The
original waveform had a peak-to-peak value of 5000 points so 20%
second harmonic is equivalent to 1000 points. The frequency of the
second harmonic is obviously double that of the fundamental, so term
+1000*sin(2*omg*t) is added to the original sine wave equation. Use
the following equation:
Ampl(p)=5000*sin(omg*t)+1000*sine(2*omg*t)
Press [Preview]. Your screen should look like Figure 5-23.
Figure 5-67. Using the Equation Editor to Add Second Harmonic Distortion.
In Figure 5-24 we created 10 cycles of sinewave made to decay
exponentially. The original expression for a s
(200 in this case) will slow down the rate of decay.
Use the following equation:
tandard sinewave is
multiplied by the term e^(-t/250). Increasing the value of the divisor
Ampl(p)=8000*sin(omg*t*10)^e(-t/250)
