Analog and digital technology go hand in hand. Both words represent a  wave. For analog this is literal and is a continuous wave sometimes  called a sine wave. For digital technology, our only way to represent  these waves is with values of 0 and 1. So digital waves come out looking  blocky as the […]

  Today, Computer Aided Design (CAD) is utilized in a variety of  fields. Engineers, architects, and industrialists have incorporated CAD  into complex designs for more efficiency and to save time.  Traditionally, designers used drafting machines (drawing tables), which  took a long time to produce blueprints. For example, if a designer made a  mistake on the […]

  Explain the basic differences between analog and digital technology. Explain the basic differences between the different numbering  systems (binary, octal, hexadecimal, and decimal) presented in this  unit.

  The  Basic Linear Shunt Regulator is similar to the basic linear regulator  with a few differences. The main difference is that the Linear regulator  uses a series pass transistor for a control component, while the Basic  Linear Shunt Regulator uses a transistor in a parallel with the load for  its control component. There are […]

We are surrounded by databases in our modern lives. Let us take a moment and reflect on the way we encounter and interact with data on a daily basis. What databases do you use every day? How are they useful to you? How are they secured? What about programs that use a database?

Mr. Tomas, the owner of a restaurant, has requested that your Web design company build a website for his restaurant. You were chosen as the web designer for this project. The restaurant is family-owned and features the family's specialty dishes. You agree to meet with Mr. Tomas this weekend to discuss the required website for […]

For your assignment this week, you will create a Web page from the given code and save it as a template. You will refer to that template each week and use it as a starter page for each page of your website. Explain the reasons why you would be encouraged to create and use a […]

Database normalization is the process of restructuring a relational database in accordance with a series of so-called normal forms in order to reduce data redundancy and improve data integrity. What are the three steps in normalizing data? What are the three goals of normalization? Why is normalization needed in the design of the database? Research and find a […]

 The FAA throws a lot of caution to the wind, especially when considering  there are no break down lanes in the sky.  Would this practice of  turning off electronic devices during takeoff and landing also be due to  the fact the new electronic devices are released to consumers on a  regular basis, which make the […]

  Oscillators with LC feedback circuits An LC Oscillator converts a DC input into an AC output. This  output waveform can have a wide range of different shapes and  frequencies, and can be either complex in shape, or be a simple pure  sine wave depending upon the application. An Oscillator is  basically an Amplifier with Positive Feedback, […]
