barcode decode algorithm
i read this paper, but there is still quite a lot about the algorithm I don't understand. Are there any other references i can look at. thanks.
barcode algorithm
I'm currently doing a barcode project, does anyone know any decoding algorithm out there that I can use to apply to this project? Thanks
Does anyone happens to know where I can obtain a copy of the application note 1014 from agilent technologies? I can not find it on their website. It's about barcode decoding. Thanks.
Re: DSP vs VLSI
thanks all for the great advice, yea, i believe i have a lot of interest in embedded system design because I like to work with a mix of both hardware and software and also because of a great professor i had, on the other hand, designing an architecture (such as a simple...
DSP vs VLSI
I'm currently a college undergraduate who is trying decide take a course of either DSP or VLSI for the next semester, both field seems to be very interesting, but considering the workload I will have next semester I can only choose one of these. So i'm seeking advice on these areas...
I'm using circuitmaker 2000 to do PCB layout for one of my circuit, and I'm having trouble placing decoupling capacitors (for each IC) on my schematic because IC chips don't show the power and gnd pins in schematic. Has anyone encoutered similiar problems?

Re: Variable Output Voltage
FoxyRick, that is really a detailed explanation, thank you!!
Since you mentioned PWM, I took a look on the web for it and I agree it is a very efficient way of motor speed controlling using microcontroller. I realized that the switch of the transistor is very fast...
Re: Variable Output Voltage
Hi, the max voltage I need is about 1A, this will be used to drive a DC brush motor.
Big Boy, can you explain to me how does your circuit work, i understand the op-amp part but not the transistor, what is its purpose? and we don't need biasing for the transistor...
Variable Output Voltage
Hi, I need to design a circuit that can output different voltage outputs(variable, say from 3v to 10v) based on certain TTL inputs from a microprocessor. The circuit should be low output impedance. I was thinking of using a digital potentiometer connected to a voltage...
How are they different? How difficult is to design a system around them, namely, the reader, the decoder(barcode), the writer (magnetic stripe)..etc? I'm working on a project in school that requires the application of access control, the core of the system will be a microprocessor taking care of...
difference between crystal and oscillator
Both elements are used for providing clocks to a system, I know that an oscillator can generate its own clock signals, and a crystal needs an accompy oscillator for the generation of clock signal (am I wrong?). If so, can we use an oscillator to provide...
different between chip or ic
I like to know the difference of IC chips that functions similarly, but are in different families. Such as 74LS14 and 74HC14, in what applications do we use the LS series, and what applications for HC series. And what are other families out there and how are they...
There are different types of IC technology out there such as the LS series, HC series, the F series. I want to know the difference between them and how each type can most optimized for different applicatioins.
A compare and contrast between these technology would be really helpful. Thank you...
h-bridge 540
The motor is drawing 0.36A at 5V.
bimbla, can you explain how did you get the formular for thermal stability calculation, and what is Icbo?
thermal calculations for h-bridge
Hi bimbla, what is SG3535, I can't find any information on the net about it.
TIP122/127 do contain a built-in free wheeling diode.
