I see other posts of people using the multi rate blocks for the 145x, and they are also listed here.

I have the latest version of Sigma Studio installed (3.13), but I don't see the multi rate blocks anywhere in the toolbox when using any of the 145x Sigmas.

Hello,

Do you have the latest release? Just yesterday I ran into an issue where I could not find something in the library and I was running the beta version of 3.13. I downloaded the new released version dated 9/7/2016 and the cells I was looking for were there. I do know they had been working on these multirate cells recently so see what revision you have?

Thanks,

Dave T

Sure enough I had a version called 3.13.1 BETA.

I downloaded the latest release and it now starts up as just 3.13, and the multi rate blocks are there.

That solves it, thanks Dave!

Hello InoJosh.

If you can either supply me with a lot of detail of the problems you are finding or attach a project that shows the issue, then I can report this to the programming team.

Thanks,

Dave T

Are there any plans to implement an FIR interpolation block instead of just upsampling?

It would be pretty convenient to have. Also, I am finding the behavior of the upsampling block to be a bit buggy - it seems like something is not working out correctly. Depending on what I put after the upsampling, one channel (dealing with a stereo signal) will end up muted.

Dave,

I created a new thread to document the issue: https://ez.analog.com/thread/88592
