The Emergence of Power Integrity Analysis
As the speed of the data signal increases, many reasons including power supply noise lead to the degradation of the high-speed signals. In low power high-speed digital interfaces, it is crucial to characterize the whole system power supply in order to...
The following attached file contains an SSH Client extension
which I made for my own use, but it may also be useful for users of the MIT Application Inventor 2 (AI2) community, or even to the AppyBuilder community (code intrinsically compatible for the last one, but not tested). This is just the...
Spring-loaded pins are rapidly finding new applications in modular product design. Also referred to as SLCs (spring-loaded connectors), this product resolves many of the manufacturing issues like misalignment, coplanarity, and tolerance stack up that can plague traditional pins and sockets...
In this blog post i will share my Graphical Lcd libraries with you which are written for xc8 compiler in MPLAB-X development environment.
The libraries functions are inspired from mikroC functions and i tried to keep most of the functions similar to the one available in mikroC compiler.

In this blog post i will share the OLED libraries with you, which are written for mikroC compiler and can be used with any other C compiler.
Following are the functions which are currently present.
void OLED_Init( void );
uint8_t OLED_Width( void );
uint8_t OLED_Height( void );

It might not be obvious to the casual user, but LTspice can be used to work with WAV files. This is a feature that most power users are well aware of but might not be obvious to new users.
Basically, LTspice allows the inclusion of WAV files in the simulation by the way of independent voltage...
Atmel releases Atmel Studio 6 beta, with support for SAM3 and SAM4 Cortex-M processor based MCUs, bug fixes, and other enhancements.
Atmel Studio 6 is the next progression in the AVRStudio 5.1 lineup, and is so named due to a new key feature; ARM device support. The AVR and ARM development...
(Speaker and speech recognition follow the same principle. So you can change this code to suit to your wish)
I see that many of you are asking code for speaker recognition. I have used mfcc for feature extraction and neural networks for pattern recognition. Here's the code

For those compilers that do not have a built-in function for swapping a byte's nibbles, a simple user function can be created:
unsigned char SwapNibbles (unsigned char x)
{
return ((x >> 4) & 0x0F) | ((x << 4) & 0xF0);
}
And a couple of function call examples:
unsigned char...
Getting a solid grasp of static timing analysis in digital circuits can be a very big challenge. It usually takes quite a bit of experience. In my view it’s not covered very well in school, and because of that it’s more difficult for new engineers.
I’ll attempt to cover this topic in depth...
SMPS is the toughest section in Power Electronics. With this subject, additional knowledge is required for choosing active and passive parts to be used in SMPS circuits. Special type of parts are often required as normal parts used in power electronics (low freq. application) may not be suitable...

Moore’s law states that the level of technology and computing power should double every two years, and so far the postulate hasn’t been wrong in more than 50 years. A group of IBM scientists have now managed to develop a data storage technique which allows for information to be stored with as...
I think everyone knows what doppler effect exactly is. I wish to write what I understood about doppler effect intuitively. If you think that I am wrong you can correct me.
Assume that a wave is coming towards you. It's time period is T seconds. Now the frequency that you see will be...

Usually we represent the gain in terms of decibel (db). Have you ever wondered why we are doing like that? I found this while I was reading about Bode plot.
The main reason for working for log is because multiplication becomes addition in log. So this reduces the complexity.
Consider a...
Magnetoresistive Random-Access Memory is a non-volatile computer memory (NVRAM) technology that has been under development since the 1990s. Continued increases in density of existing memory technologies – notably flash RAM and DRAM – kept it in a niche role in the market, but its proponents...
It was a summer vacation time, and then I was a high school student. I came across an unusual book. It said “you can do arithmetic’s at stunning speed without pen and paper” . I began to read the book and felt the magic .it was amazing, I was able to do arithmetic at stunning speed and the...
