Thanks! That was very helpful, found exactly what I was looking for.

Hello guys, I want to ask if someone over here, might have a clue/link to MCQ questions regarding the following: Calculus, and topology. Algebra (not the basic stuff) Electromagnetism. I trying searching but found very few results, maybe someone have knowledge of such websites or...

Ah didn't think about using logical operators for this task. Thought that a movbit function exist. Thanks for your answer I'll definitely use it!

Hello guys! The following question is related to the P18F2520 series. Suppose you have 2 defined variables var1 and var2 each containing 8 bits from a certain source. However I only need the 4 least significant bits from var1 and the 4 most significant bit from var 2 in order to fill up a new...

Hello guys, I am using the Smith Chart to calculate impedance in lines, adapted lines, and lines with a stub in parallele (Short circuit). I understood how to get Zin using the chart, first calculate reduced impedance, draw the circle, etc... Now I have a question regarding this, and...

That's what I ment, the values were perfectly opposite (I mean NOT(01010101) is 10101010). Anyways thanks for the answer and link

Thanks! But why use 0x55 and 0xAA why not some other random hex numbers?

Hello all, Those who usually program microcontrollers in assembly, should be well familiar with the internal EEPROM (Series PIC18F). In particular there's a register EECON2, that needs to be initialized ALWAYS with 0x55 then 0xAA before writing; Why is that? What's the main reason behind...

I don't have a solid background in quantum mechanics to be able to discuss with the more averted fellows in this domain, but what kinda mislead me was this, perhaps I misunderstood it: "Alice could send bits to Bob in the following way: If Alice wishes to transmit a '0', she measures the...

How about quantum computers? Any clue about it? Or just another figment of the imagination of people?

A big hello to all physicist, chemist, engineers and anybody reading this thread, Back in the old days, information that used to be transmitted was analogue. Later it became numerical improving immunity vs noise; However I read a couple of days ago articles about the possibility of...

It's all about you, and your interests. For other people it's the other way around, heck Aristotle and Plato wrote the most influencial books of philosophy because they like what they're doing, but I'm sure it will be a cold day in hell before Aristotle challenges Plato for a game of streetball...

Welcome abroad the vessel where everyone knows everything about anyone:D No but really, facebook keeps the data of everything you have done and posted, of course, elsewise you wouldn't be able to access your photos and friend's profile. But there's really nothing to worry about, unless you...

Generally if you can supply enough amps for all your devices everything will work fine. If your devices require a lot more amps, as posted above either something will blow, or the voltage will be reduced. Let me give you an example of an experiment I had to realize in the lab: We had a...

Hope this can be some sort of a tool to help you: Suppose your have a decimal number X and you want to convert it into the binairy number N made of n bits. 1st of all, in a general fashion: X=a_{0}*2^{0}+a_{1}*2^{1}+a_{2}*2^{2}...a_{n-1}*2^{n-1} If n=8, the highest number will be 255, and in...
