Generation of sin square wave with waiting time.

[ohkubo]

Can I use Analog Discovery 3 to output the series of waveforms shown in Figures 1 through 3?
Figures 1 to 3 are graphs that divide one signal into different time scales.
Figure 1 represents an enlarged portion of the output waveform.
It depicts a single pulse of a 50 kHz sine squared wave output at -100mV.
Figure 2 represents one complete cycle of the waveform.
This cycle will be output at a time of 1 ms.
Figure 3 demonstrates an example of graphing three cycles.

Hi @ohkubo

Yes, see the following:

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?

Hi @ohkubo

Use X from 0 to 1  : -pow(sin(PI*X),2)
or X from 0 to 0.5 : -pow(sin(2*PI*X),2)

Hi @attila

Thank you for your answer.
We will proceed with the consideration.
