Hello everyone! This is my first time posting here and I hope I can make a good first impression, and I apologize for the lack of links because of this being my first post. Currently I am working on a project for my grandfather's engineering business, and part of this project is designing a...

If we have a input voltage that has a voltage higher then the linear region of the amplifier characteristics graph, what does amplifier biasing exactly do to the wave so there is no clipping, distortion or cut-offs and saturations.

Hello all, I've been having problems regarding this attached clipper circuit and its output; i don't understand how the first part remains zero in the output wave form, isn't the dc source -2V here?, if it is then in the 1st positive half cycle AC would turn the diode on but not DC since...

I get that collector current is fixed so as collector current goes up, the voltage drop across the collector resistor goes up and the collector-emitter voltage goes down. Which is why it is basically zero at saturation. But for ac it is not zero but negative when input is positive. why is this...

I get this example from >>help eval and add a semicolon.for n = 1:12 eval(['M' num2str(n) ' = magic(n)']); end The above commands display all 12 magic square. How do I suppress the output? I only want MATLAB to assign the variables not display them.

Hello all FORTRAN geeks and geekettes, I was wondering if there is a way to get different colors for each word in a print/write statement? For example: WRITE(*,*)'This is my test sentence' Can I get each word in this write statement to appear as a different color in the terminal...

I ran into a kind of strange thing today while coding. I needed Pi in a program, so I used 2*accos(0.0) to pull it out, but my answers were slightly off. I checked the Pi calculated and it was off after a few decimal places. "Odd", I thought, and just decided to put in Pi as an assigned number...

I built a clock generator using a 555 and I fed the output to a high pass filter. It works for the most part, BUT the input voltage ranges from 0 to 5V while the output is -5 to 0 V. I can't figure out why this is happening. I'm new to EE, so bear with me.

Hello, I am new to this site and thought I would give this a shot. All my experience is in low volatge DC circuits and don't have a whole lot of experience dealing with AC but I am trying to learn. My boss and I are working on an experimental generator with 24VDC input but AC output...

Hello, I was trying to derive the transfer function of a simple inverting op amp topology, incorporating the output impedance, Ro, of the non-ideal op amp, to see how it, when combined with a load capacitance can induce oscillations (or at least ringing). I haven't been able to get a valid...

I felt like learning a bit about file input and output in C++. Tried some code, couldn't get it to work unless I made the path to the file a string literal, not a variable type. Why is this, and is there any way to get a string data type to be inputted as a path?

Is the output from a transistor sensor circuit analogue or digital? I know that you sometimes need a pull up or down resistor due to a very small current flowing through the transistor even when it should be off. However, in the circuit shown below for example, is the output signal analogue or...

1. In the Khan academy video I watched on partial derivatives, I understand absolutely everything except for the last 20 seconds which confused me. http://www.youtube.com/watch?v=1CMDS4-PKKQ Using the formula: Z = x² + xy + y² @z/@x = 2x +y x=0.2, y=0.3 2(.2) + .3 = .7 What...

My dad is an electrical engineer, I am not. I am just a dumb race car driver. That said, I want to not ask him too much about all this stuff since I want to not look like a complete idiot. I feel that some of this stuff should be somewhat common knowledge, but alas, I am drawing a blank. I...

Hi I'm just thinking over a few things and realized there's something pretty fundamental that doesn't seem to get explained often or at least very well. Maybe I'm too much of a novice, who knows...anyway... When a power supply states a power output of say, 750W, what exactly does that...
