For detailed theory read An introduction to Statistical Learning: A decision tree is a flowchart-like tree structure where an internal node represents feature, the branch represents a decision rule, and each leaf node represents the outcome. The topmost node in Read more
What is Support Vector Machines (SVM) We will start our discussion with little introduction about SVM. Support Vector Machine(SVM) is a supervised binary classification algorithm. Given a set of points of two types in N-dimensional place SVM generates a (N−1) Read more
In today’s Internet of Things (IoT) world, there is a multitude of new wireless connectivity applications entering the market each day, propelling the continuous gathering of sensors and interactions. From our smart phone telling us how many steps we have Read more
What is a memory map? The memory map of a microcontroller is a diagram which gives the size, type, and layout of the memories that are available in the microcontroller. The information uses to construct the memory map is extracted Read more
Internet of Things (IoT) describes an emerging trend where a large number of embedded devices (things) are connected to the Internet. These connected devices communicate with people and other things and often provide sensor data to cloud storage and cloud Read more
The Big Data Bang The “Internet of Things” is exploding. It is made up of billions of “smart” devices—from minuscule chips to mammoth machines—that use wireless technology to talk to each other (and to us). Our IoT world is growing Read more
Cache memory is intended to give memory speed approaching that of the fastest memories available, and at the same time provide a large memory size at the price of less expensive types of semiconductor memories. The concept is illustrated in Read more
Sensor fusion and integrated MEMS are essential tools for today’s athletes A golfer stands in the dreaded sand trap, carefully considering how to balance his weight as he eyes the ball. He takes a few practice swings. If he swings Read more

https://www.youtube.com/watch?v=_kChddN76S8 This AVR tutorial will go through the steps to create an AVR Assembly project in AVR Studio 6. This tutorial assume that you have already install AVR Studio 6 or above on you computer Step 1: To create an Read more
Autocorrelation (short ACF, autocorrelation function) is a cross-correlation of a signal with itself. By correlating a signal with itself, repetitive patterns will stand out and make it much easier to see. The (discrete) autocorrelation of a signal x is defined by the following simple Read more
As the name implies, the moving average filter operates by averaging a number of points from the input signal to produce each point in the output signal. In equation form, this is written: Where x[ ] is the input signal, Read more
STM32F7 Discovery Board have 3 ADC on board and each ADC is 12-bit ADC. The 12-bit ADC is a successive approximation analog-to-digital converter. It has up to 19 multiplexed channels allowing it to measure signals from 16 external sources, two internal sources, Read more
Today we present the first steps with the NUCLEO development boards, produced by STMicroelectronics, that can help us to move towards the ARM 32-bit world with simplicity and great performances , keeping a compatibility with Arduino expansion connectors so that Read more

Q.1 What are the key properties of semiconductor memory? Ans: They exhibit two stable (or semistable) states, which can be used to represent binary 1 and 0; they are capable of being written into (at least once), to set the state; Read more
Q.1 What are the differences among sequential access, direct access, and random access? Ans: Sequential access: Memory is organized into units of data, called records. Access must be made in a specific linear sequence. Direct access: Individual blocks or records have a unique Read more
Q.1 What are general categories of functions are specified by computer instructions? Ans: Computer instructions specify four general categories, those are Processor-memory: Data may be transferred from processor to memory or from memory to processor. Processor-I/O: Data may be transferred Read more
