16 bit Calculator design on LogiSim help]]>

is it just zipping away round there happily. Unaffected by anything else? It seems to have a complete circuit so why not.

The math when I consider the 5 ix amp source keeps coming out with zero values.

Something Wbahm said earlier got me thinking about this. Is it simply the case that View attachment 125158 Isc = 10

Or Isc = 10 + 4ix ?

Voltage Divider with Three Outputs]]>

So I've been happily calculating values for these transistor circuits. I actually analysed this one, using the methods I'd learned. Usually by assuming Vbe was 0.7.

Then ib = (Vbb-Vbe)/Rb and so on and so forth.

I realized this is a different question so I went back to my notes and saw that, for this problem, I must assume the 0.2 saturation value.

My notes state that:-

Ic = (Vcc-Vce)/Rc

However and here comes the problem:-

My notes show that...

Given two series inductors(L1 = 185uH, L2 = 571uH), in a BOOST configuration, with a mutual inductance of 0.01, what is the effective inductance?

Is the effective inductance the same as the equivalent inductance? And how are the inductors affected in a BOOST configuration?]]>

I have a figure containing a triangle and a rotated triangle superimposed at the centroid. I have joined two points of the resultant overlapped image created from the original and the rotated triangles. Now I want to do a reflection over this oblique line. I searched the internet but i cant find any equation. Eq. are provided for reflecting over x-axis, y-axis , over the line x=2 & over the line x=y but no equations are shown for reflecting object over an oblique line. One site gave...

I'm a student working on a group project and my professor thought it'd be fair to make the groups have "equal brainpower". Basiclaly this means he put all the people who haven't studied the entire semester with the people who actually care about getting an A in the class, myself included.

I've created an electronic oscillator which makes a square wave at the output, and had an LED flash on and off by attaching it to the output and ground.

For the second part, we needed to...

Ok I think I might just be getting confused because the Vs is in front of the 5ohm, rather than behind it. Doesn't make a difference does it? Like I could easily switch those around, could I? Relative to the V1 it's the same, right?

What about this current in green, designated i.

Is that the same as Ix? Ix is given in the question. What I mean to ask is, is ix coming to that node at V1? no matter what. Or is the current coming from that right hand branch, is...

Who can stop ix? Vs can?]]>

I need a help to design a 1Khz square wave with adjustable duty cycle ..

I Need to use LDR to adjust the duty cycle depending on light intensity ^^

Could anyone provide me a schematic ?

For the moment I want to ask a series of what may seem to you guys to be the most stupid questions ever posed by a human being, but to me are going to make things so much clearer.

This thing down here is driving me absolutely nuts. I can't find a loop. I can see that it's probably very simple to...

I uploaded a part of graph from my textbook.

At the graph of right below. What I concluded is ' Only if Rc is 0, than the intersection of load line and Characteristic graph of Collector-emitter is become Quotient point'

Let's say I change the value of Rc to something higher...
