    Network Reverse
AI Thread Summary
The discussion centers on recreating a dividing network based on a photo, with a focus on the angled branches and triangular transformers. It suggests that the network operates sixteen devices in parallel, with the input split into sixteen paths before recombination. The tapered transformers are likely λ/4 in length, determined by the PCB's velocity factor, and their width influences the input and output impedance. Additionally, the design incorporates a 90° separation between lines to minimize magnetic coupling. Understanding these aspects is crucial for effectively reverse engineering the structure.

Hello , I need to recreate the following dividing network .
I only have photo.
the branches are angled and the transformers are triangles ,why is that?.
could you share some impedance logic that could fit the structure below?
Is there some theory regarding this structure?
Thanks.

Where does the photo come from, what is the equipment?

That looks like sixteen devices are to be operated in parallel. The input is divided into sixteen parallel paths, then recombined to form the output.

The length of the tapered (triangular) transformers will almost certainly be λ/4, at the velocity factor of the PCB. The width of the taper, at its ends, will set the input and output impedance.

The two lines involved in each divider or combiner, separate at 90°, in order to avoid magnetic coupling between the two branches.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
