Analog-to-digital converter

BCM2835 SoC unit. Generally, the SoC (system - on - the chip) defines the structure that includes a complete microprocessor system, so there is the central unit (CPU), FLASH or ROM, EEPROM and RAM memory, digital and analog devices, and also the analog-to-digital and digital-to-analog converters, as well as serial interfaces. In distinction from the microcontroller, SoC devices are equipped with central units with comparatively large computational power, making it possible to run the…

course. The Arduino programming language used in the project is quite similar to C programming and Java programming. Those courses helped us to write the program for the project. The embedded systems course teaches about Pulse Width modulation, analog to digital conversion, and the use of general purpose I/O. This course helped us to use the microcontroller. The charging unit implemented in this project dealt with concepts and ideas covered in both Electronics I and II, such as feedback and the…

around faster. This is typically the cable that you would visibly see around the office, as it is widely implemented due to a wide range of compatibility and other features such as POE which gives companies a reason to ditch the analog phones and make everything digital for cheaper service rates. But, it’s also possible that you will see the biggest up and comer in a LAN environment, fiber optic. Unlikely to be seen in LAN unless you’re doing some serious business, but it is known to be around…

Introduction The very first fully digital camera came into existence in 1975. The camera was created by the Kodak inventor, Steve Sasson. Sasson pieced together the camera and took the first picture which was of his lab assistant. The picture was recorded on a cassette tape and displayed on a television screen. The first digital cameras sold commercially were small and could fit in the palm of your hand. Now we have everything from small hand held cameras to larger cameras with changeable lenses…

This is a simple knob that a chimpanzee could operate. Then again, a chimp has flown a rocket into space while I have not. You get the idea. Use the XLR connections to exit your studio D/A converter and then continue to your studio monitors. Place the nicely weighted knob within reach at your mix position and twist away like any self respecting audiophile would. The Level Pilot is a great addition to the studio, but here is one minor complaint…

The role of gait variability in the elderly Introduction Fall-related injuries have been one of the main causes of accidental death in older adults. Moreover, it has been shown that over 33% of adults over the age of 65 will fall every year [1]. For people between 75 and 84 years old it is the second leading cause of injury death, and for people over 85 it is the leading cause [2]. The high number of falls not only has great effect in the elderly health, but it shows a very high cost in the…

Abstract— Swarm robotics is an advanced robotics field which involves co-operative behaviour implemented on robots. Swarm robots find its applications in a large number of fields like process automation, defence, surgery, surveillance etc.In the centralised swarm robotic approach, we have a master robot and one or more slave robots. For a known environment this approach has a very less response time. The master robot is basically in charge of the slaves and controls their actions through sending…

Introduction There are many bioactive compounds that can be found around us. Bioactive compounds mostly can be found in both plants and animals. It is a compound that has an effect on a living organism, tissue or cell. It also can have an influence in our health. A few examples of bioactive compounds included flavonoids, caffeine, carotenoids, carnitine, choline, coenzyme Q, creatine, dithiolthiones, phytosterols, phytoestrogenss, glucosinolates, polyphenols, prebiotics, and taurine. Carotenoids…

1.0 INTRODUCTION It is known that radiation can be very harmful to a person’s health. According to Marshall and Keene (2006:1), with the recent expansion of diagnostic and interventional radiology, it has been noted that an alarming dose of radiation can be administered to a patient, in a single scan, without having to repeat a procedure. With the evolution of radiography, interventional radiology has become a norm in the diagnosis protocol and it is therefore important to understand the concept…

Diffuse Optical Tomography is non invasive, non ionizing functional imaging modality used for detection of brain tumor and breast cancer. A forward model design depicts the placement of laser source and photo-detector around the tissue boundary. The light propagation on the phantom takes place in Near-Infra-Red wavelength. The incident light on the tissue boundary was absorbed and scattered. The scattered rays are detected by the photo-detector and scattered voltage of the tissue was measured.…
