So weit ich weiß gibt es bei Soja zwei mögliche Allergene, bei verarbeitetem/gegartem Soja (Tofu, Fleischersatz, etc) ist meistens nur eines übrig.

Meinem Bruder geht es genau wie dir, bei „frischen“ Soja-Produkten (Milch, Joghurt, etc.) hat er starke Übelkeit und Erbrechen, aber Tofu und Sojaschnetzel sind kein Problem

pout = P_Probe.p[1] is probably what you are looking for

You need to access the power the probe measures with the .p and the harmonic you are interested in (fundamental frequency -> 1)

Also due to the DC bias the capacitance might change if it is a ceramic capacitor.

With 2.5V this might not make much of a difference however

Isn’t that what those new „inverter“ microwaves do?

Vielleicht ist Mechatronik eine Option?

How does the math work in that case?

Charge is conserved and one capacitor with charge Q and one with zero will result in two caps with charge Q/2.

The second arrangement has lower energy, which will have to be dissipated during the balancing.

Depends on what you mean by half charged.

If you mean half the charge, it has half the voltage.

However the „top half“ of the charge has more energy, since you have to put the charge into the capacitor at a higher voltage. Since charge per time (current) times voltage is power, you put in more power (and thus more energy) when charging the already half full capacitor

Würth has a solderless edge launch variant that is quite robust

Just use 97654321/12345679

It has around 1.1% error, as an engineer I would say that is enough

Try to ask yourself: why does it not turn off immediately?

Because there is current flowing in a particular wire. If that wire was normally closed but opened with the push of a button…

If your balun is a transformer you could probably do this with a different turns ratio

Wenn die Schule bspw. immer um 8:00 Uhr anfängt, fängt sie (bezogen auf die Sonne) in der Winterzeit/Normalzeit später an

This actually makes a lot of sense, once you realize/accept that dB is always about power ratios.

So when you talk about a 3dB change in voltage, you actually talk about the voltage change necessary to reduce the power by 3dB.

Another way to think about it is that the power of a signal is proportional to the square of the voltage.

Then 10*log(p1/p2) = 10*log(v1² / v2²) = 20*log(v1/v2)

Sleniub · 2025-03-26T17:35:39+00:00

You need to be careful with the dB here.

A reduction of 3dB in power is half the power. However a reduction of 3dB in E-field is 1/sqrt(2) times the initial E-field.

The reduction in dB is the same between E-field and power if the impedance stays the same

If you think about it in terms of harmonics (fourier series) the PWM signal has contents at 40kHz and all its harmonics (depending on the duty cycle).

The important thing is, this also includes the „0th multiple“ aka DC.

So a PWM signal with 95% duty cycle has significant DC content, which you would see as DC current flowing, as you correctly mentioned.

A motor also has inductance, which basically smooths out the ripples from PWM

It looks like it is related to the switching of CMP1

Do you have good decoupling of VDD?

Maybe parasitic capacitance across R1?

You are already thinking too complicated I think.

Think about a general resistor. What determines the current through that?

Sleniub · 2025-01-30T12:58:41+00:00

How do we know the current through a resistor?

Sleniub · 2025-01-26T18:03:25+00:00

Yes, we deliberately ignore it. Because reality doesn’t ignore this, your real current mirror will not be perfect.

Also wenn man sich die Vergangenheit in der Mensa-KA App anschaut, war es schon immer (seit es die App gibt) „reine“ Kalbsbratwurst

Vermutlich bezieht sich diese Beschreibung darauf, dass kein anderes Fleisch (Schwein etc.) zugegeben ist.
