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...

Many thanks for the responses. I am encouraged to enquire more. My query arises from the given question, where the current source in parallel with a diode is simply a "model" for the photodiode. I wondered what current would flow through the diode when there's no load attahced. Would it simply...

Thanks NascentOxygen and DaveE for hanging around. I am going to take this opporunity to share some numbers, which I avoided to keep things general and not burden you. Here are some: - DC at 1.24V - AC at 10mV cosine - R at 4.9K Ohm - C at 5 nF - Diode Threshold Voltage at 0.65V Clearly...

I greatly appreciate this opportunity to submit a query, and apologise for posting two simultaneous, but unrelated, queries on the forum. I simply wonder if a lower than prescribed diode voltage (0.65V) for a given I_naught be considered for the case when there is no load resistor. wirefree
