Center trace between two pads
Is there a way in eagle to center a trace between two pads? and by center, I mean directly center it with even spacing on both sides of it.
I'm asking because its easier to solder pads that aren't too close to another trace and I don't want to…

Why is center frequency of a bandpass filter is given by the geometric average of the two cutoff frequencies?
In electronic communication systems, there is a concept called center frequency. A bandpass filter has upper cutoff and lower cutoff frequencies. Center frequency supposed to be in the middle of these.
Why is the center frequency of a band-pass…

Datasheet Notation for Filter Parameters
I've been reading through the LTC1264-High Speed Quad Universal Filter Building Block datasheet but I'm having some trouble deciphering the meaning of some of the variables used in the equations for the different modes of operation. For example, in…

A question about using a dual secondary transformer as a center tapped transformer
Above is transformer in question. And in case here is the datasheet: http://www.farnell.com/datasheets/2026060.pdf?_ga=1.56694762.1111228725.1474151580
As you see this is a single primary 6V dual secondary transformer. There is no center tap. And I…

Using resistors to create a virtual center tap in PoE applications
I am designing an application where existing PoE infrastructure should be used to power a device instead of supplying each device with its own power supply.
In this application, no data needs to be transferred over the Ethernet connection, in fact…

How do I place a component in the center of the board? Altium
I'm attempting to align some components, such as an OLED display and a push-button, to the pcb board's centerline. The board was imported as STEP from Solidworks and has a non-uniform format (not a rectangle). The issue is that I've already…

2 Center Tapped Transformers together
I bought 2 center tapped transformers because I need to make 30V 2A center tapped transformer equivalent and I couldn't find anything with a 120V input.
So I got a 18V 2A center tapped transformer and a 12V 2A center tapped transformer.
18V, 2A…

Why are ratios relevant, but not the increments when defining center frequency of a band-pass filter?
First of all, here is my directly related previous question:
Why is center frequency of a bandpass filter is given by the geometric average of the two cutoff frequencies?
Olin Lathrop explained very well why the geometrical mean is taken when…
