Hey tech, thank you for answering :) I was in a hurry so I didn't have time to post the circuit, I'll attach a picture of it. It's a universal second order filter, and I'm taking the output at the BP exit. I'm looking for an analytical expression of the band pass filter so that I can extrapolate...
Hello everyone.
I'm trying to interpolate the data taken (frequency in Hz vs A in dB) from a bandpass filter with Q = 10.4.
The problem is that I'm not entirely sure about the transfer function that I should use to interpolate it. I'm trying to extrapolate the peak frequency, Q factor and...
Hi PeroK, I understand what you are saying but the books that I'm using for this class are very formal about the whole thing. I understand the mathematics but what I'm looking for is a physical interpretation of it.
Hey everyone, I've been doing some quantum mechanics but I think I have yet to fully grasp the meaning of eigenstate. What I mean is, I understand that an eigenstate ##x## is such that, if we have an operator ##\hat{A}##, it satisfies ##\hat{A} x=\lambda x## and so ##\hat{A}## represents a...
I'm wondering if anyone could give me the intuition behind Fourier series. In class we have approximated functions over the interval ##[-\pi,\pi]## using either ##1, sin(nx), cos(nx)## or ##e^{inx}##.
An example of an even function approximated could be:
##
f(x) = \frac {(1,f(x))}{||1||^{2}}*1...
Yes, but you can approach 1 from both sides. ##lim_{x\rightarrow 1^+} \frac{x+2}{x-1}## must be equal to ##lim_{x\rightarrow 1^-} \frac{x+2}{x-1}## for the limit to exist. Are they?
You're taking the limit of a constant (3) divided by something which approaches zero. What do you get if you divide a positive constant by an infinitesimal quantity?
You want to find the time the ball will take to hit the ground during its motion. The equation for displacement along the y-axis is ##y(t) = v_yt-\frac{g}{2}t^2##. By setting ##y(t) = 0##, like you did, you will find the time the ball takes to hit the ground. ##0 = t(v_y - \frac{g}{2}t)##. Both...
I see what you mean! You could numerically approximate the ##\phi (x)## with a taylor expansion. That's why we care about finding the value of ##\phi '(x)##. Thanks a lot zinq, that was enlightening :D
You should write your attempts at solving the problem else it's difficult to understand your mistake and point you in the right direction. Also your equation for work in an isothermic is wrong. ##W=Q=nKTln\frac{V_f}{V_i}##, where ##V_f## and ##V_i## are final and initial volumes of the isothermic.
