Hi, Suppose we are getting to different frequencies on 1 line. Is there any way in digital to differentiate between the two. Its related to LFPS and SS data in USB3. How can digital differentiate between the two.?
Analog PLL has a Multiplier type PD while digital one has PFD, JK or XOR circuit. nathan
Anyone can show me how to differentiate the Transistor NPN & PNP using Multi Tester (Analog & digital)? And how to ensure the Base, Collector & Emitter is correct using Multi Tester (Analog & digital)? Thanks & best regards, Keng Loong, Liew
"digital transmission" in current context usually means that the data that is actually being transported is digital. All (except optical may be) transmission schemes are analog, in the sense a square wave kind of signal is never sent in a communication system. So "digital voice" means that voice is first digitised before it is (...)
hi, Think you have hit the nail on the head there - plus as some pins default to analogue at power up, its important you clearly define them as digital.
I need to design a digital circuit that will output logic 1 and lit an LED when the input analog voltage is within a certain range (say 2-5 volt) and will output logic 0 elsewhere. A schematic would be very helpful. Thanks in advance!
I will upload PC DSP in filemanager(New) in savvas folder. DSP is software tools for digital signal processing and simulation applications more information: :):):):)):):):):)):):):)
In your case I think there is problem with compiler. 10 sig digits from FS don't mean 10bit. 10bit it mean ~0.001 so only 3 or better 4 digits are enough. I think problem could be that compiller doesn't know what to do with so many digits, or maybe you should declare constants as float, or with conversion 10bit from A/D --> float (I think you use f
Hello all, I'm trying to design a lowpass digital Chebyshev Filter IIR to get the average of sinesoidal wave with some cut's from a triac. To do that I try to use Filte.r Solution.s but if I specify 10 sig bit (to use a 10 bit ADC of 16F870) I get saturation on the filter ... Some one have tips to do that. Thank's NeuralC

Where can I get some cheap digital CCD QVGA or VGA module with digital output? 30fp/s. thanks in advance. ahgu
If you want something simple, you can have a look for dcs (digital circuit simulator). The demo currently version 1.1 and was developed under GNU GENERAL PUBLIC LICENSE. But I'm not sure whether it can interface with c or not. I will post the link later
does anyone know any links to download pdf for various topics on digital communications? Not a PDF, but a good book: Principles of communication systems by Taub Shilling A lot of theory to just about every topic. Properties of various comm channels, coding modulation, error correction, etc.
This website gives you a full explanation on how to design a digital Oscilloscope. All circuits and software is included - Tip: This design includes a few hectic sampling circuits, but if you'r only interested in building a normal scope, just look at the PIC16F84 and sheet 4 of the scematics - the rest of the circuit can be disgarded. Just take tim

Hi It is impossible to simulate pure digital amp using SPICE. The pure digital amp like apogee include Interpolation,Noise Shaping etc. How to simulate using spice? You may simulate using MATLAB. The pure digital amp is not class D amp. ynhe
Hi. I am looking for example designs of full-digital audio amplifiers. I want to use a 250mW speaker with minimum external parts, especially without DAC. There are about 2k FPGA gates available to be dedicated to filtering and PWM. The source quality is mono 8khz 8bit. Any suggestions? Marc
Hi,need help for HP 54502 digital scope trigger failer. Selftest gives Analog trigger failed. Everything on all input works well but it will not trigger. Inside is like a computer mainboard.

I've tried some from X*COR but the interface is not simple enough to
Hi all! You'll find a lot of good articles and thesis about digital amplifiers in Could be helpfull if someone colaborate posting other links. Also PWM digital-analogue convertion is interesting... Thanks in advance :wink: bicho
My opinion of IT courses in UK are that the topics are more business oriented . The IT students do get taught basic electronics and programming but not advanced topics such as OS Concepts, RTOS, Advanced Analogue and digital Electronics. I'm not very sure how the IT courses are taught in other countries and if they are similar to the courses in
who has information or circuits about 220 ac digital power meter. thanks alot
I am looking at replacing mechanical pots in a piece of test equipment with digital pots. I have had some success, but am limited by the range, and by the fact i need to isolate the signal through the pot from the dc supply for the pot. Anybody point me at some good application notes etc. thanks carrotts

The main problem it's not the circuit but the ground loop which is the pathway for noise to disturb the MCU. One solution it is to have 2 power source, with only one point of conection between the two common grounds, at the digital input board.

hello friend, I've been working on a digital volume control. The cheapest and easiest way was to raise the ground of the load and use a counter conected to a 8->1 analog switch and finally a darlington driver to pull down the load and a series resistor to real ground. Works fine and can be implemented with CMOS logic with a 3V3 lihtium cell /
