Since it is computing the time domain from the frequency domain, it might have 'automatic fixture removal' software running that will...

The cancellation occurs where the stub joins the line between port 1 and port 2. The forward wave in the stub is reflected from the...

The "trapped" energy is not relevant. Once a high-Q resonator is oscillating, no more energy is required to keep it oscillating...

I believe you can get a small but heavy RC car, inside a big lightweight ball. You must learn to drive the ball through the car. The...

I have heard the laws of thermodynamics summarised as: 1. You cannot win. (There's no such thing as a free lunch). 2. You can't even...

An open-ended λ/4 transmission line stub, appears as a short circuit in the network. λ/4 is halfway around the Smith chart, so the...

Before t=0, all voltages will be zero. At t=0, the instant step in source voltage, will be attenuated by the capacitive voltage divider...

No. The finger holes in the tenpin bowling ball, or the concentric rings on a lawn bowls ball, decide the axis of rotation when...

F = m a ; The rate at which a changes, determines the rate at which F changes. That holds for all derivatives of a.

The ball itself is a gyroscopically stabilised sphere. It will only be possible to make gentle changes to the curve and direction, or to...

Iron with a low carbon content, is a "soft" magnetic material. The steel used to make nails has high carbon content, which makes it a...

Just because you have a reasonable sounding explanation does not make it correct. Confounding factors should be tested for and...

How do you know that the steel nail is not magnetised?

It is at times like this, that I wish I had listened to my mother when I was young. On return, they learn quickly to partition the...

Hadrian's wall was built by the Romans, to prevent Romans entering Caledonia, (Scotland), where they would be subjected to asymmetric...
