    Phase relationship at high frequencies

    Just another question. Can higher frequencies be assumed that frequencies higher than the cutoff frequency?

    Phase relationship at high frequencies

    I think this works well. I got the awnser I was looking for. Thank You!

    Phase relationship at high frequencies

    Yes; this is what i was hoping to do. However, plugging w as infinity does not get the -180, so I am confused.

    Phase relationship at high frequencies

    Homework Statement Given the transfer function: Find the phase relationship between the input and output voltage at high frequencies Homework Equations NA The Attempt at a Solution My approach was to find the phase of the transfer function, which I got to be: I assumed that "very high...

    Engineering Get Current and Voltage with a Circuit with Diodes

    Basically, I think I want to know why D1 and D2 both can't be on.

    Engineering Get Current and Voltage with a Circuit with Diodes

    Thank you for the response! Aww, I'm sorry. Yeah it does look like they are bakwards (was in a rush). Thank you for that. Im sorry, but what do you mean by anode voltage? My assumption was that d2 was forward positive because:

    Engineering Get Current and Voltage with a Circuit with Diodes

    Homework Statement Find the V and I in the circuit shown below: Homework Equations D1 or 2 is off=short circuit D1 or 2 is on=open circuit The Attempt at a Solution So, my confusion lies with deciding the on and offs of D1 and D2 . My assumption is that both of them are on and that is due...

    Digital Logic 4-bit Multiplier/Adder

    Homework Statement Build a circuit that either adds or multiplies two 4-bit numbers based on a control input C(C is 1 add, C is zero multiply). Numbers are positive and negative so use two's complement. You can use muxes, Full Adder Circuits, and logic gates Homework Equations Multiplier...

    Find Thevenin Equivalent of Circuit

    Homework Statement Find the Thorton equivalent of the circuit shown [/B] Homework Equations Voc=IscRs Rseries=R1 +R2+... Rparallel=R1-1+R2-1+... The Attempt at a Solution So, I thought I should first solve for the Rsource, by shorting all of the voltage sources: However, I don't think the...

    Rth = (8 || 12) + 36 = 74.2 Ohms

    Thank you so much for the help! Could you by chance help me understnad why the 8 and 12 are in parallel?Are they in parallel because if we remove the independent sources the only "current" that should be flowing is from the a to the b nodes?

    Rth = (8 || 12) + 36 = 74.2 Ohms

    Thanks for the response again! I really wish I could use this technique, I don't understand it enough and chicked out. What I ended up doing is mesh analysis, but this time using the original 3 resistors without combining them: And I found i1=69.97 A,i2=56.67 A, and i3=26.67 A i2=ishort...

    Rth = (8 || 12) + 36 = 74.2 Ohms

    Thank you soo much for the reply.So, I did some reworking and got an answer to the problem. For the resistance, I got Rth=7.5 ohms. Before we move on, is this correct? And, is it in parallel because if we remove the independent sources the only "current that should be flowing is from the a to...

    Rth = (8 || 12) + 36 = 74.2 Ohms

    Homework Statement Find the thevenin equivalent of the cicuit shown below with V=500 V and i=10 A Homework Equations Voc=Vth Isc=VN The Attempt at a Solution [/B] So, to solve this, I used my instructors method of first finding the Rth. So, what I did was set the independent sources to...
