Engineering Fourier transform -- Is this an error in my textbook?

AI Thread Summary
The discussion centers around a perceived error in a textbook on Fourier transforms, specifically in the equation presented in Chapter 2 of "Fundamentals of Wireless Communication" by David Tse and Pramod Viswanath. The participant highlights a potential correction to the equation, suggesting it should read F(ω)=γQ(ω)+(1−γ)F(ω)Q(ω). There is frustration expressed regarding the lack of proofreading in academic texts, as it leads to confusion for readers. The conversation emphasizes the importance of accurate references in educational materials. Overall, the consensus is that the textbook contains a mistake that needs addressing.

It looks like a mistake, the book writes the following:

I believe (2.4) should be: ##F(\omega)=\gamma Q(\omega)+(1-\gamma)F(\omega)Q(\omega)##. I don't understand these pitfalls in books, they don't make someone to proof-read the text?!
I mean besides me the reader... of course. :-D

"The book" is not really a great reference, What book and what page? Jeez

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...
