Measurement of transformer with a vector network analyser (VNA)

Even voltages smaller than that can be measured since the VNA can fiklter ("average") the measurements. When you take measurements, perhaps there is an averaging capability on the VNA (may ...

Why are analog signals preferred for high-frequency applications?

Digital signals are useful models but are ideal concepts and don't exist in physical form. So if you think about logic gates, truth tables, and digital waveforms on paper, it is similar to thinking ...

Why are analog signals preferred for high-frequency applications?

Via Fourier, digital signals are square waves and so have inherently higher bandwidth than an analog signal, all other things being equal. Intuitively, this is due to all the sharp vertical edges in a ...

Why doesn't the whole signal get absorbed by the termination resistor in high-speed designs?

The termination resistor at the end of the line does dissipate almost all the signal energy, which is why it prevents reflections. If it did not dissipate the incoming signal, that would mean it is ...

Why doesn't the whole signal get absorbed by the termination resistor in high-speed designs?

We normally parallelly terminate with a matching (50 ohms) resistor in highspeed designs. Normally, the load/receiver is high impedance but if we terminate it with a 50 ohm resistor wouldn't the whole ...

Why doesn't the whole signal get absorbed by the termination resistor in high-speed designs?

The termination is there to match the impedance of the line and prevent reflections. It will absorb power, but not enough to load down the driver significantly. Your load (receiver) needs very ...
