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...
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...
The switching is required in many applications at low as well as at high frequency. RF MEMS switches are the specific micromechanical switches that are designed to operate at RF to mmWave frequencies. MEMS switches usages some mechanical movement to achieve a closed or open circuit in the Radio...
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...
Using the PIC32MX250F128B, I decided to make a simple audio player. I wanted to play back good quality audio from a large memory space - a microSD card. So, I made this WAV player that can play back 16-bit 44.1kHz WAV files with 12-bit stereo audio output. Of course that's not all it can play...
With power LED's mounted boards with adequate copper surface or aluminum surface area (~1 sq.in/Watt) cool emission of light can be adapted to almost any fixture with mindful avoidance of glare.

In Part I of this blog, we saw that we can construct two partially correlated signals, x1(t) and x2(t), as:
\[
\; \; \; \; \; \; \; \; \;\; \;\; \; x_1(t) = \sqrt{P_1}s_1(t) \\
\; \; \; \; \; \; \; \; \;\; \;\; \; x_2(t) = \sqrt{P_2}ρ∗s1(t)+√(1−|ρ|2)s2(t)ρ∗s1(t)+(1−|ρ|2)s2(t)
\]
where P1 and...
Note: This blog is split into two parts because edaboard limits the number of pictures and equations per blog. The second part can be found here: [link].
Introduction
It is often useful to be able to generate (real or complex-valued) signals with specific cross-correlations. In the simplest...
I was recently asked how to estimate the frequency of a noisy sine wave over a short capture. In this context, 'short' means the total capture duration relative to the period of the sine wave. So we may have, at most, a few periods of the sine wave (or, at worst, less than one period). Here is...
Coding Spacing is commonly generally defined by the range between data transitions to prevent DC content of data. Bi-Phase which is self -clocking but reliable and used in early Telephony 1.544Mb/s repeaters then tri-level coding was used. Similar starts in ethernet coding were used.

Power measurement methods for RF
**Peak** = instantaneous maximum read with storage memory ( digital or Analog )often measured with Log Amplifiers calibrated in dBm for 50 or 75 Ohms
**Average** = time interval averaged over specified interval
Both above are computed by voltage detection...
Design site has error in the design calculations for RMS >Peak.
In the end the RMS voltage of the transformer should only be slightly more than the LDO Vdc if the optimal parts are selected.
Assuming you want 5V,1A regulated choose LDO regulator with minimum drop otherwise 2.5V typical may...

Hello Everyone!
This presents an attempt to measure phase difference between two sinusoidal signals in simulink.
There is no existing block in Simulink for that.
I have made frequency as a Global Parameter.
LSNI-BT02
The previous post discussed a simple transistor based inverting MOSFET driver ie. LSIN-BT01. It consisted of a Level-Shifter stage followed by a transistorized totem-pole output stage. This post discusses a NON-INVERTING version of the previous driver. For quick reference this...
LSIN-BT01
Much of the work that I had done till now was confined to my mind or scattered everywhere in bits and pieces. The difficulties were soon evident. So I promised to write. With an year of experience (academic) in power-electronics, I quickly realized that MOSFET gate drivers were...
This article is intended to be a quick guide on calculation of transformers used in AC voltage stabilizers which employes series topology. Such model is rarely used in low power equipments due to the relatively more complex control system required for drive the switching devices, but is...
We often plot some data on a graph and wonder if there might be a simple mathematical function to describe what we see:
In many cases, a polynomial approximation would be particularly useful. That is, we want to describe the line in the form...
MIT finds 15-year-old scouring trash bins for parts.
When MIT discovered Kelvin, he was living in utter poverty. But that didn't stop this engineering whiz kid from building something amazing.
Introduction
I didn't want to buy an expensive variable power supply for my small, low-power projects, so decided to make my own. I couldn't find much inspiration online, so I thought I'd write up my design in detail here in case it helps anyone else. Circuit schematics, layout, source code...
Equipments such as Inverters and Rectifiers employ power modules as IGBTs, MOSFETs and TRIACs based on compact packages (modules). These components are mounted just above heat sink structure, and unlike PCB based packages, offer the possibility for assemble adopting an alternative approach...
Multilayer Inductor
An inductor constructed by layering the coil between layers of core material, the coil typically consists of a bare metal material( no insulation), this technology is sometimes referred to as "non-wirewound", the inductance value can be made larger by adding additional...
When dealing with displays which haven´t character pattern at desired size, we need to insert character maps in the code program. Once draw entire table is a task somewhat painful, the next step is take a search on the Web for some available map file.
However, after find it and put the map on...
Requests for sample C code to deal with a matrix keypad is a recurrent question, what motivated me to share here some tips on an alternative implementation, not so widely employed.

In the rush to get a product out the door, programmers often ignore code maintenance — a key aspect of application
development. For applications with short lives, this rush may not pose a significant problem because once deployed, no one will touch the code again. Embedded systems...
