Differential amplifier

The aim of this project is to develop an Electrocardiography (ECG) amplifier circuit from scratch. The main challenges include amplifying the desired week signal in the presence of noise from other muscles and electrical sources. As this semester was about transistors we had to use transistors at some stage in this project. The project was successfully designed and built in two ways: one with solely using operational amplifiers and other using transistors as differential amplifiers. Electrocardiography (ECG)/ Background The heart is one of the vital organs in the human body. The heart behaves like a pump that circulates blood and oxygen around the body in order for the human body to function flawlessly. Waste products are removed from the body…

So you 've decided you want to be a rockstar, eh? You 've decided that you 're going to join the likes of Hendrix, Clapton, Page, Stevie Ray and Slash as a rock n ' roll and guitar icon. Well, before you get too famous and lose yourself in either your music or drugs and alcohol, you have to get a guitar to begin with. It can be daunting to go into a guitar store and see millions of guitars, some for $200 and some for $2000. So which ones should you go for and what should you be looking at? Well…

summer of 2001; my oldest sister, of the two, would always drive around in our hometown playing her favorite alternative rock tracks. It was calming driving the backshore, with the waves crashing into the rocks. It was like I was at peace sitting in the backseat of her jeep, just watching the ocean; I could feel myself hearing Stone Temple Pilots. At that moment, I was sure I found my liking, and that would be rock and roll. When artists like Radiohead and the Foo Fighters came on, I’d be so…

effective trick and a common technique. In a nutshell, use a reamping box to record a dry signal to your DAW while listening to the tailored tone from your amp. Next, use the reamping box to play the dry performance back to your guitar amp. You can dial in alternate tones using the same performance that has already been captured. Mic the amp as usual and record these alternate tones till your heart’s content. This is a great way to layer different sounds while using just one take. Let’s…

in mind the style of music you will be playing. It is no good buying a "shred-master" metal machine if your primary musical influences are jazz or blues. Take a look at the players you often listen to and see what they are using. Most players will cite a particular model or type of guitar as being best for a particular style of music. An example would be using hollow body electrics for jazz or Telecasters for country music. However, there are no rules, and the general wisdom is at best a…

Silence, after a hard day of school, all I wanted was to relax to the ballads of 50 cent, and I got silence. The bass must have shifted an exposed wire and shorted the amplifier, I fixed this a few times before that it almost became routine, but it was not a shorted wire. Troubleshoot, no solution, what could it be? My set up was almost perfect, lacking solely in achievable decibels. Second hand children science encyclopedias along with Questions and Answers books got me this far and for a…

(1:1,000) injection, auto-injector – 1 application intramuscular to be injected as directed. Initial Differential Diagnoses M.G. presented to the clinic today clean and intact. She is well developed, well nourished and in no apparent distress. I examined her face, neck area, bilateral hands, trunk and upper and lower back, and other parts of her body. She has diffuse eczematous lesions in various stages. Macular, popular, erythematous rashes were discovered on her extremities and trunk. Her…

Fundamental Theorem of Calculus The Fundamental Theorem of Calculus evaluate an antiderivative at the upper and lower limits of integration and take the difference. This theorem is separated into two parts. The first part is called the first fundamental theorem of calculus and states that one of the antiderivatives of some function may be obtained as the integral of the function with a variable bound of integration. The second part of the theorem, called the second fundamental theorem of…
