I know higher the frequency more likelihood of causing resonance in similar size molecules, thus increasing abosorption chances.
Then why do satellites communication use so high frequencies (L, K band etc.) ?
I want to know why these pass through the ionosphere and not abosrbed...
Correct me if I am wrong but I have seen North America the best for engineers' salaries followed by other EU countries like Germany, France and then UK,Spain etc.
I was surprised by some ppl.s comments on salaries in scotland. Do engineers get paid more there as compared to england?
Which areas have most RF/Microwave jobs in Canada ?
I know of the techological hubs like Ontario and Waterloo but I am wondering if somone can give me more specific information on RF jobs ..
Many Thanks !
It seems that average salaries are only slightly better in Canada than here in UK..
I was wondering howz the jobs opportunities for RF Engineers in Canada now.. After nortel bankruptcy, confidence is a bit low and it seems only RIM is hiring ..
- What is VSA? Is it different from a normal spectrum analyser?
- Are there any links to detail design inside a cellular phone?
- Does anyone know a specific research area for next generation smartphones?
I have an interview at Nokia for a 'RF Engineer' position. I have knowledge of generic RF stuff but I was wondering if anyone can specify more on What kind of RF skills are really needed for such a position ?
Is it true that GPS needs a direct line-of-sight link with the antenna and satellite ? If it is so, I was wondering how can a GPS based system work to track containers kept inside a vehicle ?
rf beacon tracking
I need to make a presentation on what factors to consider in designing a tracking system embedded in the Cash-In-Transit products.
I have googled such systems and also on this board, most of the people suggest a GPS-GSM embedded system i.e. finding the location...

Re: Help for "Error : does not hold value outside clk e
Here is the part of code that deals with the signal 'S_PLLValid'. I tried to mark the signal as bold but apparently it doesnt highlight under the code tag, so I've indicated using arrows.
I am trying to compile a VHDL code written by another person. I am getting this error for a number of signals.
The Quartus Help file apparently does not provide any details on this error.
Can anyone help what the reason is and how can the error be corrected?
I know that integer's range is upto 2^31 - 1. But does this condition apply to the every number in the equation that would result in an integer ?
signal factor : integer ;
factor <= (2**48) / (300E6) ;
factor_bin <= conv_std_logic_vector (factor,20);
vhdl std_logic_vector type conversion
So how should dividers be implemented in VHDL for Quartus?
The thing is Quartus compiler was inferring the "/" operator as a divider when the numbers involved were integer types but not for unsigned !
I am looking to implement SAGE Algorithm. My present understanding is to go through a series of literature illustrated by the following pyramid.
I am basically around the second from bottom to last layer/step of the pyramid.
convert real to std_logic_vector
Heres my problem:
1. 'integer' is only 32 bits. I am working with numbers greater than that uptil 48 bits. (e.g. 4.456E13)
2. My idea was to use 'real' numbers for all computations and then convert them to a std_logic_vector of 48 bits to output ports.
