Homework Statement What are the effects of poles and zeros of a transfer function on its magnitude graph. Note: The Transfer function is discrete. Homework Equations zeros= roots of numerator poles=roots of denominator The Attempt at a Solution I really don't have any idea. I...

Homework Statement Why the output DC voltage of the center trapped rectifier is half that of a bridge rectifier??

[SIZE="3"]Series resistors: Requivalent=R1+R2+R3+...+Rn ______________________________________________________ [SIZE="3"]Parallel resistors: ( 1/ Requivalent) = ( 1 / R1) + ( 1/ R2) +...+ ( 1/ Rn) OR you can use the following equation if you have two parallel resistors...

Homework Statement Explain what is meant by "DC Offset" in an amplifier and how can you eliminate it ? 2. The attempt at a solution I think it is the deviation from the real voltage, but I am not sure

hi, Homework Statement I am asked to generate 1000 normally distributed random numbers and then plot the scatter and histogram graphs of the data. The Attempt at a Solution I used : randn(1000) and it generated the random number, now how can I plot the graphs? from where...

thx, it is clear now :)

anyone ?

which agent will reduce the temperature in the first case, and why it is not present in the second case ?? can anyone explain more please, I am running out of time.

thx but, it is still not clear

maybe pressure

the question is based on this simulation : http://phet.colorado.edu/simulations/sims.php?sim=Gas_Properties I don't really know, In one case T decreases and on the other it doesn't although Vo and Vf are the same for both cases.

I think when the volume is increased fast, the molecules does not have enough time to exchange heat with the surrounding environment but I am not sure.

A fixed amount of gas molecules are trapped in a box. when the volume of the container is incresed slowely, the temperature decreases. However, when the volume is increased quickly the temperature don't change or decreases slightly. Explain why the temperature decreased more when the volume of...
