Circuits and Electronics: Dependent sources and amplifiers
http://circuitsandelectronics.blogspot.com/2009/07/dependent-sources-and-amplifiers.html
11 Temmuz 2009 Cumartesi. Dependent sources and amplifiers. All right, good morning. So today, we are going to talk about what is both a basic device in itself, the amplifier, and it also serves as a real key example of both nonlinear analysis and small signal analysis. So, to quickly review, we talked about a few primitive elements: resistors, voltage sources, and so on. One of my favorites, the Thevenin method, the Norton method, or the method that involves composition, that is very quickly analyzing c...

Circuits and Electronics: Sinusoidal steady state
http://circuitsandelectronics.blogspot.com/2009/07/sinusoidal-steady-state.html
11 Temmuz 2009 Cumartesi. OK Good morning. Let's get going. As always, I will start with a review. And today we embark on another major milestone in our analysis of lumped circuits. And it is called the "Sinusoidal Steady-state.". Again, I believe this will be the second and the last lecture for which I will be using view graphs. And the idea here is that, just like in the last lecture, there is a bunch of mathematical grunge that needs to be gone through. You use much easier techniques, which I will tal...

Circuits and Electronics: Nonlinear analysis
http://circuitsandelectronics.blogspot.com/2009/07/nonlinear-analysis.html
11 Temmuz 2009 Cumartesi. Will try it again at the end of this lecture and you show you that stuff hopefully next time. For today we are going to start with nonlinear analysis. Before we do that I wanted to do a little bit of review. We also learned the method involving composing resistors, the voltage dividers and so on and solving circuits intuitively. And we also looked at the node method, which is kind of the workhorse of the circuits industry. So when in doubt apply the node method and it will get y...

Circuits and Electronics: Second-order systems - part 2
http://circuitsandelectronics.blogspot.com/2009/07/second-order-systems-part-2.html
11 Temmuz 2009 Cumartesi. Second-order systems - part 2. Before I begin today, I thought I would take the first five minutes and show you some fun stuff I have been hacking on for the past three years. This has to do with 6.002 and circuits and all that stuff, but this is completely optional, this is for fun, this is to go build your intuition, this is to check your answers, whatever you want. The idea here is that it is a, that is kind of defocused. Any chance of focusing that a little bit better? Good ...

Circuits and Electronics: Incremental analysis
http://circuitsandelectronics.blogspot.com/2009/07/incremental-analysis.html
11 Temmuz 2009 Cumartesi. OK, good morning all. So before we begin, I just thought I'd show you a little news item that I happened to read that was very relevant to what we covered recently in 6.002. So you recall when we did the digital section a few days ago last Thursday, we talked about a switch. And pretty much any advancement that can be made to the basic transistor can have a 10 million to 20 million times effect because there are that many of them on a single chip. So I thought that was very ...

Circuits and Electronics: Second-order systems - part 1
http://circuitsandelectronics.blogspot.com/2009/07/second-order-systems-part-1.html
11 Temmuz 2009 Cumartesi. Second-order systems - part 1. All right. Good morning, all. So we take another big step forward today and get onto a new plane of understanding, if you will. In the last week and a half, our focus was on the storage element or storage elements called inductors and capacitors. It has to be two independent energy storage elements and resistors and voltage sources and so on. And what we end up getting is what is called "second-order dynamics." And much as first order circu...Befor...

Pipeline Inspection Gauges PIG: Pipeline Inspection
http://pipelineinspection.blogspot.com/2009/07/pipeline-inspection.html
Pipeline Inspection Gauges PIG. 9 Temmuz 2009 Perşembe. An operator needs to maintain a safe pipeline, and ensure it has a long and profitable life. Consequently, he must consider maintenance measures that are both cost effective, and prevent. Failures or large repair bills. This Section of the Workshop is aimed at answering the type of questions a pipeline operator should ask himself before he considers an internal inspection. The paper starts by covering maintenance and inspection methods in general.

Pipeline Inspection Gauges PIG: Temmuz 2009
http://pipelineinspection.blogspot.com/2009_07_01_archive.html
Pipeline Inspection Gauges PIG. 10 Temmuz 2009 Cuma. Which Methods should an Operator Use and How Should they be Optimised? The great advantage of this scheme is that it can:. I rank all the pipelines within a group (or sections of a pipeline) in terms of probability of failure, and consequences of failure,. Ii determine which pipeline (or section of a pipeline) is most in need of some type of maintenance measure,. Iii determine which maintenance measure to use. 9 Temmuz 2009 Perşembe. This Section of th...

Circuits and Electronics: Inside the digital gate
http://circuitsandelectronics.blogspot.com/2009/07/inside-digital-gate.html
11 Temmuz 2009 Cumartesi. Inside the digital gate. All right. Good morning. Let's get started. So the last lecture we showed you how to go digital. The fact that going digital had some key benefits for us. And what we'll do today is go inside the digital gate. Let's do a quick review. We began life by observing nature. We said those Maxwell's equations are tough. Let's simplify our lives by discretizing or lumping matter. So we got the lumped circuit abstraction. If I was a sender I had to adhere to some...

Circuits and Electronics: State and memory
http://circuitsandelectronics.blogspot.com/2009/07/state-and-memory.html
11 Temmuz 2009 Cumartesi. I will be replacing Professor Agarwal today because he is away. I am one of the recitation instructors for those of you who have not seen me. We will talk today about a neat application of RC networks and expand those to application in MOS memory systems. To connect with everything, we will get back to the basic circuit that we have been discussing so far. And you recall the circuit that we have been studying, the canonical RC with an input voltage function of t. And, again, as ...
