AI Thread Summary
The discussion focuses on implementing an echo canceller in MATLAB, specifically expanding the transfer function 1/(1+(alpha)*exp^-sT) into an infinite series to derive the impulse response. The user has completed initial steps but struggles with the series expansion and truncation process. They express a lack of experience with MATLAB and seek guidance on how to write the necessary code, mentioning that their teacher indicated it could be done in just a few lines using specific commands. The user is looking for assistance and clarification on these topics. Overall, the thread highlights the challenges of transitioning theoretical concepts into practical MATLAB implementation.

I have done numbers 1 and part of 2.

I got the transfer function to be 1+(alpha)*exp^(-sT). For part 2 i was able to get that the transfer function for the echo canceler was 1/(1+(alpha)*exp^-sT). This is where my trouble begins, i do not know how to expand it to an infinite series and then from that getting the impulse response of the echo canceler and then truncating that. I would move on to the Matlab part but i have never done MATLAB before and do not even know where to begin on that part. My teacher said this program could be written in just a few lines and all we would need for commands were filter, sum,zeroes and plot. Any help would be amazingly appreciated. Thanks yall.

Does no one have any idea how to do any of this...even a little?
 
Thread 'Have I solved this structural engineering equation correctly?'
Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
