The thing I find about continued fractions, and ladder attenuators, is that evaluation from right to left attenuates the numerical...

If you can evaluate the exponential ladder as a fraction, p/q, which you can, then the result must always be a fraction, and so the...

Feed a PRBS or a wide-band noise into one line, while you terminate both ends of the other line, then look for the signal in the other...

Simply fixed value ladders always do converge to a recurring continued fraction, and since an RCF can be evaluated with a quadratic...

Your spoiler is numerically correct. For each stage, you add conductivity in parallel, then resistance in series. Note that conductivity...

Structural plywood on edge is lower cost and more rigid than wooden beams. Salvage some shipping pallets that have a sheet of 5/8" =...

The vertical legs are in axial compression, with little bending moment. The horizontal members carry a load evenly distributed along...

Maybe, the dust plume ejected above the surface was illuminated by direct sunlight, while the crater is a hole full of shadow.

How to make it less sensitive to alignment. Perhaps, the fit between the leg and the pin box could be opened to allow increased slop or...

No. Impedance is a vector sum of resistance and reactance, ( R + j X ). An induction motor has a small reactive current in quadrature...

The VFD was expecting to drive an inductive motor. You raised the frequency of the LPF by 470 / 2.2 = 200 times. That explains why the...

I need to see the data points to know if it shows the zoomed in sampling rate, or the real rise time. I can see the motor drive...

Science is not a secret, and it is too big to be seen by one generalist in its entirety. On this website, only the accepted models of...

@PAUL GRAHAM If you can place a strip or sheet, of foam or rubber, under the aquarium, that will tend to reduce point loads between the...
