I don't see what was wrong with our logic, though. The current can't change instantaneously through the inductor. Prior to the impulse, the current is zero. Once the impulse occurs, it shouldn't be able to jump. It follows that the current in the inductor is equal to the current in the resistor...
The transfer function of a passive bandpass filter has one zero and two poles.
The filter is:
Signal -> L -> C -> R -> Gnd,
where the signal is the input and the voltage across R is the output.
H(s) = \frac{sRC}{s^2LC+sRC+1}
Initial value theorem states that it's impulse response has...
Ok, I am looking over stuff for an exam. I am a bit confused on something. When conductivity is zero, a medium is lossless. Zero conductivity means infinite resistance. For infinite resistance, no electrons will flow, but an electric field can propagate forever. A wire has high conductivity, so...
Hello,
I was given a voltage regulator today (to provide -5V to an op amp). I was told that I could create a -5V signal from a +5V and a ground. I was told that the ground was converted to a neutral level. I understand what that means, but not why or how it works. Could someone explain that to...
Hmmm... that is interesting. I was hoping to be able to resolve this in my simulation. I guess I won't be able to. I am just doing a simple logic sim, and it's not really fit to handle things like this. Thanks for the feedback. PF never let's me down!
Right, it makes sense to think about it like that, but to actually simulate it, I need an initial condition. I had previously been considering all gates to initially be at 0. But this seems to give rise to the problem I stated earlier:
At time 0:
Both gates output a 0.
The NAND sees a 1...
I am doing a discrete event simulation of logic gates and I have come upon a problem. I have set up a system similar to a ring oscillator. I understand that this system should not oscillate, but after thinking about it, I'm not sure why not. The system has one input, 1 fed into a NAND gate. The...
Why is it safe to suck the helium out of a balloon, but it is dangerous to ingest alpha particles? I guess the main question is what is the difference between an alpha particle and a helium atom?
Aren't they both written as \stackrel{4}{2}He?
Homework Statement
Two large area parallel plate capacitors, labeled P and N, are connected as shown in the figure below. The charge on each plate is indicated in the figure, in μC.
I. The capacity of N (on the right) is 27.5 μF. Calculate the capacity of P.
1.34×10-5 F (Correct)...
