Is the reason for guitar "tone suck", i.e. loss of high end frequencies with impedance mismatching, actually due to high reactance?

Yes, or most likely so. We can model the pickup like so: simulate this circuit – Schematic created using CircuitLab Now, I'm not well versed in guitar pickup design and typical values, but my ...

Is the reason for guitar "tone suck", i.e. loss of high end frequencies with impedance mismatching, actually due to high reactance?

It could be. If you have a long cable, it adds more capacitance, i.e. capacitive reactance. High capacitive reactance means the capacitance shunts current more for high frequencies so impedance is ...

What is the purpose of a shunt element in a balun?

This circuit and the question regularly re-appears in electronics and ham radio forums, and I believe the circuit is a misused or mis-represented lattice-type LC balun, see a correct presentation in ...

Coax cables, impedance matching and BNC extensions

We can easily model situations like this using simulators like Micro-cap 12: - The top trace is the originating pulse of 10 ns with a rise and fall time of 10 ns The next trace is after the 50 Ω ...

Balun converting 100ohm single-ended trace to 50ohm single ended for spectrum analyzer

Can I connect the 100ohm single-ended signal to a 2:1 balun to convert it to 50ohm single-ended for spectrum analyzer? No, that would make it 25 Ω compatible. The turns ratio squared defines the ...

Balun converting 100ohm single-ended trace to 50ohm single ended for spectrum analyzer

Your second balun is actually an "un-un" and would usually just be called a transformer :) So, can you use 2:1 winding rate transformer to convert 100Ω single-ended to 50Ω single-ended? Not ...

Incorrect Output of RF Mixer

Your 100 MHz preamp is a common emitter amp stage. It's not popular, because the capacitive feedback from the collector to the base knocks the gain down even at 100 MHz except in case it's compensated ...

Coax cables and input impedances

This voltages have rise times of the order 500ns Roughly, for 50 Ω coaxial cable, the velocity of propagation of a signal is around 200,000,000 metres per second. So, in 1 metre, the signal takes ...

Can I add a resistors to add speakers?

While you technically can do that, there might be reasons why you might not want to actually do that. Assume a speaker is a simple 4 ohm voltage driven load (it's not really, it's basically an ...

Can I add a resistors to add speakers?

You sure can, and it will cost you half of your power. The resistors must be high-wattage to handle all the power you threw away. Your 100-watt channels turn into 50-watt channels. Those big, ugly, ...

Can I add a resistors to add speakers?

Yes, that should work. I use series resistors with my speakers as well, because the impedance of the speakers I have is less than the minimum allowed for the amplifier. Has been working fine for 20 ...
