    Gain Margin, Open or Closed Loop?

    You use the open loop TF.

    Trig Identities that I can't get a grip on

    Correct!

    Trig Identities that I can't get a grip on

    You will need to use the identities tan(A+B)=(tanA+tanB)/(1-tanA*tanB) tan(A-B)=(tanA-tanB)/(1+tanA*tanB)

    Implement XNOR using NAND gates ?

    Three NAND gates can be combined to produce the double AND plus OR function. The rest are just those required for the invert operations.

    Engineering Laplace help on a DC transient RC circuit ? PLEASE

    Yes I did. CEL has made the right suggestion for obtaining the solution. You should end up with something similar to that which I posted in the pdf.

    Solve Ideal Diode Problem: V & I Calculation

    Remove D2 from the circuit. Work out the voltages at the nodes where D2 was connected. Decide whether D2 would be forward or reverse biased. Proceed from there.

    Engineering Laplace help on a DC transient RC circuit ? PLEASE

    It's not clear what the actual circuit comprises, but reading between the lines I think the Laplace form of the voltage Vc should be as given in the attachment.

    Understanding Power Factor and Utility Penalties

    A purely reactive load still draws current and gives rise to undesirable joule heating losses and voltage drops in the power distribution network conductors and components (such as transformer windings). That loss is not recoverable. Allowing very low power factor conditions to prevail could...

    Mechanics of Materials - Internal Moment

    For the portion of the tube along the X axis due to the tube weight Moment at B = (1/2)*g*12*(0.2)^2 = 2.35 Nm For the downward 60N force Moment at B = 0.05*60 = 3.0 Nm For the rod portion along the Y axis Moment at B = 0.2*0.4*g*12 = 9.41 Nm For the upward 60N force Moment...

    Engineering Resistors and circuit requirements

    You are on the right track. It only remains to work out how you make each of the required resistors from 20 ohm values. A Hint: For example if you put 2 x 100 ohms in parallel you get 50 ohms. So how many 20 ohms in parallel would make 10 ohms? Once you get a handle on that idea, it should be...

    Many batteries in series (dangerous?)

    I've seen something similar done with 9V cells which clip nicely together in an end-to-end series chain of any arbitrary length. Seemed dangerous to me once you got above the safe ELV.

    Bridge and center-trapped full wave rectifiers

    If you mean for the same transformer primary-to-secondary ratio but with the center tap used in one case (with 2 diodes) and with the the total winding used in the other (with 4 diodes in a bridge configuration) - then yes that's true. In the first case only half the total secondary voltage is...

    Can Rapid Inverter Switching Cause Harmonics in a DC Line?

    Don't know if this is what you have in mind, but might be of interest. Shown is the DC source current, it's FFT and the circuit from which it came - not mine - PSIM Demo.

    How Do You Calculate the Leakage Resistance of a Capacitor?

    I calculated R_{leak}=1.062\times10^{14} ohms Sure it's a big value - not something you measure with a multimeter! - but an ideal capacitor would have infinite leakage resistance.

    How Can I Improve Signal Transmission and Reduce Noise in High Magnetic Fields?

    You can also incorporate gain and filtering in a fully differential MFB stage such as described in the following link [PLAIN]"focus.ti.com/lit/an/sloa064/sloa064.pdf"[/URL]
