This is a great video. I've been a fan of Mike Engelhardt since his introduction of LTSpice but now QSpice is the likely where I'm moving to. This is a great video showing the features. How's about doing one on the verilog interface as well?

Don't remember if it a mistake or it cancels out in other place.

Hello Gregory, how are you? You disappeared and now only make videos in English. Anyway, better in English than no videos at all. The other day I was watching some of your videos on Wagner Rambo's channel. Flip-Flop

Где вы находите резисторы на 50 Ω ??, сколько я не искал в своих наборах, нам только 47 Ω.

Depending what you are doing 47 ohm will be fine

2:27 - Noise doesn't have a time frame? Do you mean, this particular measurement of noise doesn't have a time-frame? i assume you could measure noise over time, if you wanted to. Might be useful. - "It doesn't matter the timeframe, it looks exactly equal." What looks equal? Each of those traces looks different, as you switch the timeframe. - What's being traced here? Just noise? Or noise plus signal? What's the difference between the thick solid central band and the fuzzy top and bottom? - Thx!

Looks to be good content (this is your first video I came across) Just one request add English subtitles please. (at first this might seem a lot of work but let youtube generate it, then you just edit it.)

Why not just add a 100 Ohm resistor? Is that because we do not want to reduce the Q value?
@AllElectronicsChannel
@AllElectronicsChannel 15 күн бұрын
Because the resistor would dissipate the power, not increasing the delivered power.

@@AllElectronicsChannel Thank you Gregory for your response! I was having trouble understanding the intuition the parallel-to-series conversion/mental model yesterday and I see now that it is just a way of explaining how we can, for a given frequency, increase or decrease the impedance of the load by using power storing elements. Your video was very helpful in understanding what we are achieving by constructing matching networks!

Awesome how you connect between empirical and theoretical! And, pretty slick how the calibration setup works! I imagine that it can also be done by using a short, open, and 50R dummy load at the feedpoint?

Simple thing that it is almost impossible to get maximum power transfer because the output impedance of a source is never matches with the impedance of load

Very nice presentation. I have used MATLAB Simscape for mixed-signal (analog/digital) control loops but it has a high learning curve and is expensive. QSPICE has great potential here.
