Smooth transition

[marinajordao]

Hello everyone!

basically I want to do what is in the picture attached.

I have an array of ones and zeros, which are later converted into waveforms. So I want these waveforms representing zero and one, when transiting the waveform representing 0 for waveform that is 1, and vice versa, has smooth transition. I've tried using filter, but it only applies to all signs, and not every 0 and 1. Someone help me?

Thanks!

Oversample your zeros and ones array, low pass filter to smooth it, THEN multiply by the sinusoid function.

I try to do that but doesn't work. I send you my code. do you understand my code?

I don't have LabVIEW on this machine, please post an image or VI snippet of your block diagram. Also, it would help if you tell me exactly in what way it 'doesn't work' .

Too small for me to read really, but it looks like you're 'filtering' individual samples? Pass the whole input array through the filter, but upsample it first.

So, you have to tell your code to apply the window to every 0 and 1, here's a quick draft:

Yes, This is exactly what I needed.

Thanks a lot guys!
