I'm working on data exchange between my stm32-F103 and atmel AT24C02 serial EEPROM on my starter board. I have did the programming based on I2C peripheral and DMA. the pull ups are 4.7 k. when I debug the program the result is fine and the data inside the EEPROM come out but when I...
frankly I've noticed that it can be a snubber but the way it is being used can provide a path for ac voltage of ring signal that was my second question.
the important thing is the path which the ring signal can induce to other side of transformer. can't we use them...
the below image shows the line interface of a dial up modem. the DC loop, ring detector, isolation transformer and hook relay are clear. the question is what does the RC circuit (shown in red) do?
when modem is not in operation and a ring signal comes, don't you think the high AC...
what is your evaluation from this autocorrelations of two signals. the important for me is the amplitude of the noisy samples between the repeated samples. neglecting the high amplitude repeated samples, can i suppose it a random signal?
what about this...
Would you please tell me what is the difference between standard I/O Buffer and Global Clock I/O buffer?
how can i explicitly instantiate an I/O Buffer component for each top-level I/O signal in xilinx ISE?
I am also designing a 2nd order EF structure by VHDL. I've Read Mr. Peter's theory and I agree with you. I'm not sure yet. The structure adders show overflows but I don't have any idea about stability. I'm in doubt for my correct design.
Need IEEE Paper
Would you please send me this paper:

I need a formula of sigma-delta modulators, which makes relation between these parameters:
1- Input signal Amplitude,
2- Order of modulator,
3- Number of levels of the Quantizer,
thanks in advance
Can anyone provide me the methodology for Delta Sigma ADC/DAC SNR measurement in simulation?
I used SD Toolbox from Mathwork, but i didn't get the true answers. i'd like to measure SNR for some DC input signals. would you please help me to know the principle of SNR...
could you tell me what is this block in SDtoolbox,please?
is it as same as a quantizer?
how does it work? what is the DAC and ADC output lines? what is the usage of ADC line in an all-digitall sigma-delta modulator modeling?
how can i use this block? especially in determinig the N-ADC...
Hi dear friends,
I need to know something about signal restoration. i have some distorted audio samples by severly filtering and background noise and i need to restore them by matlab. can anyone help me to know about common practical methods that exsist. can the LPC method for...
I don't think so. the providers in the pdf document presented in delsig.zip, say:
"The Delta-Sigma toolbox requires the Signal Processing Toolbox and the Control Systems Toolbox."
in the help document provided in SDToolbox.zip:
"The SD toolbox is a toolbox created to simulate...
I need delta-sigma modulators simulation . I downladed 3 different toolboxes from matlab file exchange center. but i don't know what differences they have. they are :
can you say me their differences and which of them can help me?
If your computer is standalone (or have no internet connection), i suggest you "Antivir" which you can find on (it's free) :
i think it is the best !!
If you want to protect your computer on internet, you need internet security...
