Generating Sine wave is very demanded job in power electronics field. So do to me too. I read some topics over the internet and found many ways to generate a sine wave. As most of you are really interested in generating sine wave so I’m writing today about it here.
There is some different ways...
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...

that implements a very simple socket; note that its operation is performed 'one-shot', which means that only one command is sent ( and its respective response, read ) at a time, and then the socket connection is closed. So, be aware that it is not a...
HSM-20G is one of the most common humidity and Temperature sensor. This sensor is fully analog type. The outputs are analog voltages rather than any digital signal.
The datasheet indicates that the output pins need some extra devices with it. here is the connection diagram:

Hi Dear All
When i learned the class D amplifier , i was , 16 years old . and the problem was that i tired from dissipative amplifiers such as Class AB and C . ( and all of the times i like learning new things )
So , i read many articles from big companies , such as International Rectifier ...

After reading the following announcement I thought it might be of interest to forum members utilizing the 8051 and variants in their designs.
While the various Microchip PIC series of microcontrollers are well known and utilized by many of the forum members, the Microchip series of 8051 are...
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...

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.
