I will try to help
1) U r sampling some analog signal say x(t) with some sampling rate say Fs (let Ts = 1/Fs) .. Be confirmed about the Nyquist criterion (both Frequency of x(t) and the bandwidth).. now suppose you have done it correctly
2) there is 4 bit ADC i.e u have a quantiser and follow...
Basic but intresting Q...
I would put my knowledge in this .
Data rate ... It depends on how fast you can send the data . , as rate is also there .ie at what clock you r sending the data .. 4 example
1) if one need to send a 50 bit of data every second .. then he requires a 50 Hz clock that...
what is zero cross dpll
Time recovery is easy , when you have data bits , you know the bit duration but its an integral value and you cannot find exacttly the zero crossing of the bits. So to find the zero crossing of the bits very pricisely you need the phase information (QPSK) and to know the...
Frankly speaking .
The confusion you are in is not a great deal if u are clear about the modulation /demodulation scheme in ur communication system .
Infact u dont need any filters , you can work without filter if you are working on CDMA signals.. because the signal is below noise and there is...

Hi
Even I'm having problems with tuning. I saw the swanson and wenzel's paper and also ansoft HFSS workshop presentation by Dawson RF design where they have shorted out all the resonators but two. Then they have manually tuned it for proper resonance and coupling bandwidths. For...

hi!
I am in search of a VHDL simulator which satisfy these requirements.
1. I wanted to automate the simulation process, i.e. say i have 1000 separate piece of VHDL code, and i waned to simulate all of them, and store the simulation/ test results in a data file to be...
While recently reading a document from nera research on HFSS simulation, I cam across the following reference
Folgerø, K. (Nera Research), Step-by-step procedure for design of waveguide filters with HFSS, Ansoft HFSS User Workshop, Los Angeles, January 2001
I could not find it anywhere. Could...
waveguide iris filter
Hello All,
I'm trying to design a waveguide iris filter in HFSS. I'm using the matthaei's design procedure for the design. When I try the design on mode matching software, the results are good but when I simulate it on HFSS, the results are no where close. I'm able to see...

Hello All,
Could anyone please explain what are the different matrix solvers available in IE3D. What are the difference between these and when should we use each one of these.
Thanks
Re: IE3D sim. confusion
Hello All,
I would like to comment about the repetitive behaviour of transmission line filters. The repeating passband is an inevitable property of transmission line filters. Let me explain with a simple end coupled microstrip BPF.
Just try to think what waves can be...
I have not posted this question to ansoft but I searched in their reference list on their website and could not find anything on this topic. Guess I've to figure it on my own. I'll let you guys know once I'm done but meanwhile please reply if anyone got any success in this
filtros combline con hfss
Hello All,
I am simulating a cross coupled combline filter on HFSS using Irises for cross coupling. I have got the normalized coupling matrix but now I am facing difficulty in finding out the Iris dimensions for the given cross coupling values.
What I did was that I...

I have Holux-210 GPS Mouse .. it has USB connectivity ... I want to use it for my handheld
Actually speaking it o/p RS-232 data which is USB converted .
Please help me
