Octave:3> File Operations
Generally Matlab/Octave scripts work on processing section of data which are generated from some kind of experiment or other events e.g. image processing. It is not possible for a user to enter value of each pixel manually in a processing algorithm. It is needed to read the image file directly and import data into variable in workspace.
Octave:2> Conditional Execution
Conditional execution and loop are the backbone of any algorithm. These maintain the proper flow of algorithm, for a successful execution.
Octave:2> Scripts and Algorithm
We need to change the settings, modify a variable. It is not convenient to retype everything. Scripts are the perfect solution or such cases which contains expressions in correct sequence

Vectors and matrices are very useful for dealing with systems of linear equations and inequalities. This article takes more practical approach to use Octave/Matlab for Matrix operations.
DIY two-channel 120W DC power supply
DC power is the basic need for any electronics project to start. Though batteries are good for small projects and also recommended due to the stable supply of current. But with increased power demand for more sophisticated projects batteries don’t seem a very good option to work with. A good bench supply or power adapter is handy and can be easily procured, but there is no match for custom-tailored design, specifically suited for the need. This is the story of a DIY two-channel 120W twelve volts fixed DC power supply.
Octave:1> Built-In Functions, Commands, and Package
In mathematics, Function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. This concept is borrowed by programming languages to simplify the code by avoiding unnecessary repetition.
Octave:1> Expressions and operators
Expressions are the basic building block of statements in Octave. It can be created using values, variables that have already been created, operators, functions, and parentheses....
Octave:1> Variables and Constants
Octave showing the perfect compatibility with MATLAB keeps its tag of being called open source clone of MATLAB. This article is a continuation of the series dealing with variables and constants in Octave.
Octave:1> Getting Started
GNU Octave is a very powerful suite for its numerical, graphical, and programming capabilities. Despite being open-source this software suit can completely replace MATLAB (except few...
GNU Octave – Scientific Programming Language
GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab.
Engineered to doom – Red flags for PCB design
this article can be taken as both ways, as a revenge 😮 or a guideline for what not to do. The decision is purely up-to reader. Technie X has decided, clues from personality should be used to model into design decisions.
Decoupling – Path to power integrity
The effectiveness of the decoupling at high frequency is dependent on the number of capacitors used as opposed to the low frequency where it depends on the value of the capacitor used.
Strategy for component placement
The best PCB layout starts on the foundation of component placement. It is wise to not rush the process. Every extra iteration should add up niche a feature or remove a short-coming. Picking up a small detail and reducing the effort of routing by this creative process is the most challenging phase in PCB design life-cycle. But it’s totally worth it.
Selecting a PCB stack-up for EMC compliance
Good PCB stack-up is very effective in reducing differential and common mode emission from the board. Choosing a PCB stack-up in the design process is analogs to the foundation for a house. Hence selecting it carefully can save a lot of costs afterward occurring towards mitigation of EMI/EMC issue.
15 PCB Layout guidelines to achieve EMC requirements
The PCB layout doesn’t have a fixed set of rules, hence every designer generally employ a set of guidelines while using their engineering judgement. These Guidelines set out best practice to reduce the cost of boards and to minimize the risk of errors arising during manufacture.
Checklist for error-free optimized PCB layout
A good list of checks to make before committing the design of a new printed circuit board is an essential ingredient for quality assurance.
4 steps to review the PCB layout
While some portions of the circuit performance are dictated by the schematic and BOM, the PCB layout finally decide the fate of design. During layout, we often need to use engineering judgment on the trade-off between the size, cost, testability, and manufacturability of the board.
Board bring up: Giving life to the design
Board bring – up is a planned process whereby an electronics system, including assembly, hardware, firmware, and software elements, is successively tested, validated, and iteratively debugged in order to attain manufacturing readiness
100 Point checklist for schematic design
We have categorized the checklist in multiple sections for a systematic checking. There are many details that go into making a successful first – run design, and this checklist helps prevent bugs from marrying a healthy design otherwise.

Introduction to diode
The diode is one of the basic non-linear circuit components which conducts the current in only one direction. In operation, it is analogous to a mechanical check valve that allows the flow of fluid in one direction and blocks the flow in another direction. Similarly, diode also allows the flow of electron in only one direction, known as the forward direction. This unidirectional behavior is also known as rectification and is used to convert alternate current(AC) to direct current(DC). It would not be wrong to call this basic element as the flag bearer of the electronic edge.
