Generating signal as shown in the image in labview

[GoviRe]

The above attached is the only thing I have at hand adn I want to generate similar to the signal shown in the image.

Can someone guide me for this.

You still have not provided enough information. What is this 'project report' you are referring to? What is the source of the original signal? What is the original signal supposed to represent? Have you tried anything? It was suggested to start with a sawtooth waveform. Have you done anything with that?

Hi Todd_Lesher,

This is what I was looking for.Can you please post the vi you made.

thanks

Can you explain of how you changed the input signal image I posted to the PNG (the one you are using as the input singal iamge) alogn the vi you made.

Oh, shoot. I thought I posted a snippet. I deleted the source.

First, I cropped the png file to the smallest area that included the white line. I used gimp2, but paint works just as well.

Then, I loaded the png file, converted it to a 1-bit pixmap, rotated it 90 degrees (transpose 2d array), and saved the index of the first True value in each row.

hello,

we have a trouble in connecting source to sink since the type of the source is different from the sink.

the type of the source is double(64 bit real(~15 digit precision))

the type of the sink is 1D array of double(64 bit real(~15 digit precision))

plz help us to rectify it

Hi Todd_Lesher,

I tried the way you explained but I am not getting of how to rotate 90 degrees and I need some modification to get the final as yours.Can you help me out in modifying the attached as the same of yours.

Thanks.

Patan,

Think these are just basics.

You already used the functions of the most uncommon blocks.

Anyway I added it in attachments, you could just use the snippet from Todd.

Hi KoenR94,

The vi you posted is reading the PNG image but it is not showing up the final waveform.The input image I fed is attached below.

Can I know what is the problem with this.
