Hi Rick!Well...it's a bit comforting to know that the author whose book I read in undergrad is also puzzled. :)
Hi MichaelRW, thanks for your answer and for writing the code for me. But the book's text (section 2.7) and exercise problem 2.20 both state that we need to pass...
Hi everyone!I am solving a computer exercise in Andrea Goldsmith's Wireless Communication book. The problem statement is: "the simulation first generates a white...
Hi Rick,Thanks for your guidance and lessons. I've learned a great deal from this post. Thank you.I hope you get some time for the sink problem soon. :)
Hi Rick,At least there's something new I learned from all this, esp. since you experimented with other b's and a's and still ended up with the same problem when...
Hi Rick,
It seems like I have figured it out (OR made a fool of myself, I'll let the grown-ups decide).
As suggested by drmike, I used MATLAB's second order sections...
Hi Rick,I'll run your code.But this imperfection would mean that even designing second order sections and cascading them won't work because the sections would have...
I am just attempting this DSP semester project on MIT's site (I mentioned it in one of my replies above) and one of the tasks is to have such a filter and notice...
Hi Rick,I did the same before posting the problem here. I tried N = 2 and N = 3 and things were okay but when I tried N = 10, I got crazy results.The coefficients...
The reason I used convolve is that say I have a polynomial (x+1) and I wanna raise it to the second power, then the way to do that is to convolve x with itself....
Hi everyone. I am attempting to implement a higher order all pass filter of the form in MATLAB. The filter coefficients b and a are given byb = [0.5314, -3.1345,...
Hi Rick Lyons,Yes, this w_sub_k is undefined. Actually you have to go through all the steps, meaning that for a different K (the authors showed the derivation for...
Comparing the effort/cost involved in explaining the "obvious" versus the effort/time spent by new researchers in understanding the "obvious", I think authors should...
I know that papers these days build up on a lot of literature and hence are very compactly written. There is also the issue of page limits. I've heard that papers...
So using all the helpful comments, I have figured out the problem. The problem with the initial samples was that I was not doing that step out of laziness, but Sanjit...
Thanks. Yes, zero padding at the beginning is what I was referring to. But I wasn't aware of the zero padding at the end. I'm replying from my phone and I haven't...
JBrower, you are right about Rick's comments - helpful as always. I shouldn't have used a random input, rookie mistake!My code works fine except for the starting...
Thank you, Rick Lyons. This is very helpful. I'll go through it, see where I went wrong and how I can modify my code accordingly. Thanks.
