you are missing quantum mechanics! an electric field is a vector field of electric potential, and you get potential with charged particles. you also get potential with moving magnetic fields, as per faradays law (or is it amperes law?). i think the "and" in your quote could be replaced by...

to be frank, I have no idea what a correction element refers to in this case. any controller must be either open loop or have feedback (or feed-forward, but that is unlikely to be the only form in this case), a bang-bang controller working in open loop mode would be the equivalent of a (human...

hmm, i think you are reading the summation notation wrong, Cn+1 doesn't come into the equation, only Cn, the previous term. C1 = C0*C0 = 1 C2 = C0*C1 + C1*C0 = 2 C3 = C0*C2 + C1*C1 + C2*C0 = 5 C4 = C0*C3 + C1*C2 + C2*C1 + C3*C0 = 14 and so on...

have you been introduced to an equivalent circuit model? I would guess that you have to compare your results from the 150k loaded experiment, to the results from the open and short circuit experiments.

though i don't know the context, level of detail, system you've been studying etc... heres a few pointers. if that statement is false, how does the controller know when to switch? I think those two statements must be equivalent, I would be very surprised if they could have opposite, uh...

core loss in a transformer is made of two separate components, the eddy currents, and the hysteresis losses. eddycurrents increase with the change in magnetic field, while hysteresis losses are dependent on the peak amplitude, and capped at the total saturation point of the core. can you...

mention of heaters and transformers suggests some form of AC power is being controlled. is it possible that the code senses the AC signal and implements phase angle modulation control? this may appear as variable period PWM to somebody who wasn't aware of this method.

I see a difference in your scope, those peaks are clipped asymetrically. it should be noted that DIY guitar effects pedals are usually built by random trial and error, by people who haven't studied electronic design. http://www.diystompboxes.com/wiki/index.php?title=Simple_mods

if the diodes were the other way round, the fets would add to the clipping threshold, and probably soften the edges up a bit. http://www.generalguitargadgets.com/richardo/distortion/index.html that page has some info, it says edit: ha ha, on closer look, i think that's all the page says.

surely any cpu clock running at 2 GHz is going to be an electrical oscillation at 2 GHz? so despite being very low power, and designed to pass EMC tests the principle is the same. is a 500 THz tank circuit possible? that might be incredibly efficient lighting!

but we don't know what they are, as they are dependent on the input, so we can't write either one off as irrelevant. whether or not you care about what the signal is, in order to state that the output of P = /bcd + /d, as you have done in your answer to clause 2, you need to be sure that those...

its highly likely yes. look in the microcontrollers datasheet, it will should you the ranges that the adc can convert

np. I find it quite strange that your lecturer told you the wrong answer, be sure to ask them for clarification! ps, do you recognise any other type of flip flop in the truth table for the drawing http://img141.imageshack.us/img141/8427/jkok.jpg it is a valid conversion, just not for...

again, I have zero experience with verilog, but since it compiles down to the same thing as VHDL, i would imagine the structure of what you can do is similar. in the code posted below, i and count are dealt with in exactly the same way. so unless you have declared them as different datatypes...

the value of clk doesn't generally get included in a truth table, because the operation of a clocked flip flop is not dependent on its value, rather on its edge. a truth table for a clocked device is generally supposed to be interpreted as "what happens when you get a triggering edge on clk"...
