Analog Signal Loop/Switch Control?

Click For Summary
The discussion centers on a custom project involving 16 analog sensor loops requiring flexible configuration for inputs and outputs. The user seeks to combine loops in various sequences and assign specific channels for output, while also addressing noise concerns for a monitoring system. They are considering using FPGA or PIC chips but express a preference for discrete components, having previously used relays. The possibility of USB or communication port control is also mentioned as a desirable feature. Suggestions for multiplexing or switching mechanisms, such as the CD4016, are offered to help achieve the project goals.

Analog Signal Loop/Switch Control?

Hello fine people of this board. I have been working on a custom project here for a year or two and I'm stumped at this point. I am working with 16 analog sensor/signal loops (16 ins and 16 outs). There would be 2 main signal inputs, and 2 signal outputs also...

I need to be able to combine any of the 16 loops (say loop 2 and 6 only, or 4 and 5 only) in any configuration, before or after each other (say loop 6 then into 2, or loop 2 then into 6). Also, I need to be able to designate a channel to each loop (say loop 2 to 6 then out on chan1, and also loop 4 to 7 then out on chan2). Noise is an issue as well, it will be used for a custom monitoring/radio data system. I have been looking into FPGA chips as well as PIC chips but not really sure if I need all that. Does anyone here have any thoughts?

I would really like to have this done with discreet components but it seems a bit much for that. I have been able to build a device like this using relays. But, could never come up with a way to move the placement of the loops in the chain. USB or Comm port control would be an added bonus. Thanks to anyone with any ideas! Sorry if I left something out or am going about this the wrong way. I'm completely self educated when it comes to EE and design...

Thread 'I thought it was only Amazon that sold unsafe junk'
I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
