Hi, Could you tell me any process how to validate the digital_to_Analog converter. Is there any method to communicate digital signal and digital Input of DAC. Thanks for comments..
Research about "all digital PLL". Circuit is simple, connect input signal to ADC input. Other option to convert sine to square wave and process with digital input.
Why would you only take the feedback loop in the FPGA? You can process the audio chain perfectly in the FPGA. Do you actually understand the concept of digital signal processing?
You need to determine characteristics of the noise in the frequency domain. The process of digital filtering consists to reduce components of the signal lying within a specific bandwidth.
Do you know how a microcontroller or a cpu for that matter generates a sine wave? Well, fpga do the exact same thing. You may want to look up Direct digital Synthesis and DAC.
You can refer digital signal processing with Field Programmable gate arrays by U. Meyer Baese. However you need to have knowledge of vhdl programming and designing the entire process..you can refer Peter.J.Ashenden to read more about vhdl.
Hi, usually digital signal processing is attached to process analog signals by converting them to a digital representation and perform the function(e.g. filtering, analysis etc.) with a fast digital processor. It could be a simple microcontroller for slow (...)
Hi All, I'm in the middle of a mixed-signal design project using the TSMC 0.35um 2P4M process. I've done some chip layouts in 0.5um before during undergrad, but this is my first time using 0.35um. I have a few questions and concerns: I've created some custom digital standard cells to do the limited digital logic that (...)
What is the best way to learn the basics of digital signal processing fast? I have a good mathematical background, but I learned Fourier series a very long time ago in a Numerical Analysis class, and I never took a DSP class before. I need to know the basics of signal processing for a job interview that is (...)
Everything is analogue*, it's just a matter of how we generate, process and interpret that analogue signal to give it, transfer, and infer from it information. *That's not true, everything is digital thanks to quantum physics. That's not something that usually needs to concern us though.
Hello, I have some doubts that I would like to resolve. I'm in process of buying development kit based on Spartan chip family. The idea is to buy dev. kit, to get familiar with it and than to develope my own fpga board. Main application would be in digital signal processing. Virtex family is out of option for having (...)
Hi all, In the process of digital to analog conversion, the thermometer code output, corresponding to the digital value of the input signal, activates the unit value of the analog entities (which may be current or voltage sources). The analog output is the summation of all those activated analog entities. Please can (...)

The question is very unclear (with a light smell of confusion). FPGAs are programmable digital logic devices. Which noise signal do you want to process with your FPGA board? Are you talking about digital signal processing? If so, which analog-to-digital conversion capability (...)
Hello all, I have a (probably stupid) question about a clock signal provided by a rotary encoder on a motor. I have to use this digital signal to sample an analog signal with an external ADC, this signal is in fact the clock of my ADC. My question is : can I create a process with the (...)
Hi, You can try the digital lock in amplifier. What basically it do is, it detects the signals in vey overwhelming noise background and even it can provide high resolution measurement of relatively clean signal over several orders of magnitude and frequency. Thank you.
Dear friends, Here I'm Saathis. Currently I'm doing my final year project. Below are detail n help i needs.... Information: The system name is Speech Door Access System. user have to register before use. After register they must use provide password to access door. User have speech password via microphone. The password will be checked eith
If your process does not provide IO cells for analog and digital IO then you can make up a simple setup, but the possibility of ESD failure might be highly possible. If you dont have them available here is a starting point. You would first need to know what size pad your bonder can bond too (pad size and pitch). I would start making your pads 10
I am wondering if the op amp can process digital signals. If it can do this processing which considerations I have to take care? Thanks
Yep analog and RF designs are often more suited to Bipolar. CMOS more for digital. Although, obviously now there a lot of mixed-signal designs.
