That is indeed the definition of an eigenvalue problem. Why does one type of differential equation lead to such a situation, while the other doesn't?

The operator E in the time-dependent version, as well as the operator H in the time-independent version, is a differential operator: former of time, and latter of space. So, they both clearly result in differential equations. The question becomes: what makes one an eigenvalue problem...

Section 3.3 titled 'Solutions of the time-dependent Schrödinger equation' states in its 1st line that the time-dependent solution is not an eigenvalue equation: The same section ends with a comment on eigenstates: How do you reconcile this: are solutions to the time-dependent equation...

I am interested in following your suggestion. Please annotate as briefly as convenient, Sir.

Here's a view: You see how the perspective view squashes the 160yd width of the polo field.

Namaste & G'day! Imagine a helicopter view of a Polo ground. It's length & breadth are known. Now you are seated where the blue dot is. Your view is such: How do mathematicians calculate the distance travelled by a ball from the second perspective? From the top view, this would be...

Thank you for responding. Hope today has been good one. My apologies if the problem statement wasn’t ostensible. The two signals are in the first line; flipping, which is one of the steps of discrete-time convolution, occurs in the second. Problem Statement: Perform convolution sum on the two...

Please see below my attempt to perform the convolution operation on two discrete-time signals as part of my Digital Signal Processing class. I suspect my folding operation, i.e. flipping one signal about k=0, might be the cause. Ostensibly the answer of the convolution sum evaluated at n=-2...

I do now. Thank you, Sir.

As I keenly await Respected Members to respond, I am taking this opportunity to better explain my procedure. Given quantities & circuit: * The last quantity on the right is V_S (it's calculated) The procedure to determine R_D is as follows: 1) Calculate V_S for given I_D and R_S (calculated...

I greatly appreciate the opportunity afforded by this forum to submit questions. I am presently tackling a 10-part question, fourth of which this post is concerning. Values provided at the start are: R1, R2, k, V_T and I_D. In the previous 3 parts, Source Resistor, Transconductance (g_m) and...

Thank you, willem2, for taking this forward. It seems I didn’t comprehend your solution from your earlier post. Voltage across the diode I already have, or don’t I? I believe we agreed that the voltage is back-calculated for the current Io, and it comes out to be 0.626 mV. Next, I am...

Many thanks to all senior members and mentors who have posted here. I am proceeding with the information you have provided. I am required to find two quantities next: (1) voltage across the diode with no load, and (2) voltage across a load that is at a resistance that affords maximum power...

Thank you for your detailed feedback, DaveE. I'll be mindful of that when I run through my calculations. Your concern about AC source frequency stands out prominently. I address it here: You have stressed that omega has repercussions on whether the diode is on/off. But the way I see it is...

Many thanks, DaveE. I noted that battery model in Prof. Razavi's (UCLA) text on microelectronics. I am glad to have made a start! I'd appreciate if you could review my approach thus far: Consider diode is always on Forget DC Convert AC, R and C to phasors Invert R & C phasor values to obtain...
