    Interpolating data of a bandpass filter with Q=10.4

    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...

    Interpolating data of a bandpass filter with Q=10.4

    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...

    I What is the physical interpretation of eigenstates in quantum mechanics?

    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.

    I What is the physical interpretation of eigenstates in quantum mechanics?

    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 Understanding the Intuition Behind Fourier Series?

    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...

    Calculus Troubles: Finding Limits and Understanding 0/0

    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?

    Calculus Troubles: Finding Limits and Understanding 0/0

    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?

    Solving Systems of Linear Equations (Echelon Matrices)

    When you add 18 times r3 to r4, the last term of row 3 is 16/14*18 not 16/4*18

    Physics projectile motion question

    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...

    Physics projectile motion question

    It's okay, just look at your result and think of what the problem is asking you

    Physics projectile motion question

    I also think that the question isn't about how far the ball will travel, but after how much time it will hit the ground

    Physics projectile motion question

    If your ##V_0 = 62\frac{km}{h}## and your angle is 35°, why are you using ##V_0 = 52\frac{km}{h}## and an angle of 50°

    Stirling Cycle Problem

    You're not accounting for the number of moles in your expression for the change of internal energy of the system

    Question about the implicit function theorem

    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

    Stirling Cycle Problem

    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.
