    Simplifying Convolution Properties: Understanding the Delta Dirac Function

    How were they able to simplify the following? I understand the distributive property and how the convolution component of the delta dirac function worked but I do not understand how the second term convoluted becomes what it is. Thank you for your time

    Signals and Systems Theory Question

    Thank you for the response sir but I really do not see how that works. How can one simply say that 2.5cos(3t) = 2.5e^(3jt). I thought cos(theta) = 1/2(e^j(theta) + e^-j(theta)) determined by the subtraction of 2 mcclauirin series.

    Signals and Systems Theory Question

    Homework Statement [/B] How are we able to go from the first line to the second line and then the second line to the third? Homework Equations Euler Identity: e^j(theta) = cos(theta) +jsin(theta) The Attempt at a Solution This problem is more about preliminary theory in my opinion so I tried...

    Electronics Determining Op Amp Gain.

    Yes you are absolutely right my A will be 4004 but the correct answer is indicated to be 1001 in all previous editions. the circuit provided is all information. The only additional information says Vo = 4 V and v1 = 1.0 V

    Electronics Determining Op Amp Gain.

    Charles thanks for taking to the time to help out as well. I think gneill has the right idea of how to approach this problem so if we are to approach the problem assuming it is not an ideal OP amp what would I have to change in my solution?

    Electronics Determining Op Amp Gain.

    I strongly felt the same way as well Charles. But this is a problem directly from my textbook and it has not been modified for the last 3 editions so I'm assuming it is correct. Thank you so much for the response though. EDIT: It is definitely very strange compared to the Operational amplifier...

    Electronics Determining Op Amp Gain.

    Homework Statement Determine the Op amp gain of the following circuit. V1 = 1v Vo = 4 V Homework Equations A = Vo/ VI The Attempt at a Solution Using voltage division I determined the voltage for the node at the +ve terminal VI = V1(1k/ ([1000 + 1]k)) = 1/1001 V Vo = 4v Given Therefore...

    Maximum Power Transfer Ideal Transformer

    I see thank you for the response. When dealing with this problem would you determine the current I by dividing the given voltage by the sum the 2 impedances. Then we can say that S= I^2Z so P = the real component of S

    3 Phase Systems Theory and Procedure -- Determining Average Power

    Homework Statement Consider the 3 following Scenarios: 1. 2. rms value of line voltage is 208 V Three equal impedances, 60 +j30 W each, are delta-connected to a 230-V rms, three-phase circuit. Another three equal impedances, 40 +j10 W are wye-connected across the same circuit at the same...
