In the same program, create another function called AddNoise
that calls the first function NoiseGen. AddNoise should add the
noisy waveform from the NoiseGen function to a sine wave.
AddNoise should have two inputs, one for the NoiseGen
amplitude and one for the sine wave. It should have one output
for the result.
Build a simple main program with a slider for the noise
amplitude, and the Virtual Source Function Generator (sine wave,
Freq = 100 Hz) for the good waveform to add to the noise. Display
the resultant waveform.
Solution—UserFunctions, Step 2
Figure 294 shows a solution for step 2.

In the same program, call the AddNoise function again, this
time from a Formula object, taking the absolute value of the
result. Display the absolute value waveform on the same
display. Next prepare to edit the AddNoise function. Turn on
