On a number of component data sheets I've been reading, I see two different voltage supplies, VDD and VDDIO. They are usually called the analog and digital supplies or the power and I/O power.
My question is what are these two different supplies for? I understand that these components may be...
Hmmm... I'm pretty sure I didn't reverse the polarity of the cap. Is there any other way I could have caused damage to it?
Also, is it possible to check whether the cap is working or not using a multimeter or anything without having to pop it off the board?
So, I have a PCB with a cap in it and wanted to monitor the voltage level of it. I hooked up an oscilloscope to it and then heard a pop. I think the cap popped. What did I do wrong here? Am I not supposed to hook a cap to an oscilloscope and is it possible to verify if the cap is what caused the...
Let's say you have a sinusoid x_ref. And you have done also some processing on some other signals to produce an estimate of x_ref, called x_i. What would be a good way to find the error between the two signals?
I can do a point by point mean absolute error, but is there a good way to normalize...
Hi guys,
I am an electrical engineering student in my Masters who is also dealing with some topics in biomedical engineering. I'm not sure if anyone can help me out here, but does anyone know of any papers or journals that talk about algorithms used to find diastolic or systolic blood pressure...
generalized cross correlation
Can somebody explain to me what GCC (Generalized Cross Correlation) is? How does it differ from regular cross correlation?
Thanks.
hcs12 microcontroller
Hello all,
I am currently in my project course beginning to program a HCS12 microcontroller made by Motorola. It's a Adapt9S12DP256.
I'm confused as to how to program it. Basically, where do we start? We were given some sample code by our professor in C and are using...

It should be on a lot of things. All batteries have them to label which side is positive and which is negative. Circuit diagram voltage supplies use them to indicate the positive and negative sides to indicate current flow or voltage levels.
analog electronics
Much like the others, I recommend Sedra and Smith - Microelectronics. We've been using the 5th edition of this book for three Electronics courses at my University in the EE program.
Hello,
We are currently amidst our 4th year design project and we need to model a sensor for distance. Our professor has recommended us an ultrasound sensor model for reflection coeffecient. Ideally, we'd like to have a model of reflection energy/signal vs. distance for an ultrasound device...
