Thank you for your wonderful answer.
I was able to create a similar screen.
However, there was one point that I couldn't quite understand.
The difference is that the formula on the "Wavegen - Custom" screen is "-pow(sin(2*PI*X),2)".
When set using the same formula, two pulses will be output as shown in the attached waveform.
If I specify "-pow(sin(PI*X),2)", the waveform will be one pulse.
Please tell me what is the difference in this number of pulses?
