Understanding Fourier Transforms

Click For Summary
The discussion centers on using the Fourier transform to analyze the function x(t) = A sin(w1t) + B cos(w2t) for its frequency response and spectrum graph. Participants emphasize the importance of showing work when asking for help and clarify that a frequency response typically relates to transfer functions in circuits. The conversation also prompts the user to identify the frequency components present in the time domain function. Understanding these components is crucial for accurately sketching the frequency domain representation. Overall, the thread highlights the need for clarity in defining terms and demonstrating effort in problem-solving.

Hi guys, can someone help me solve this.
Thanks.
I think that is with the Fourier transform.

You were asked to show your work when reposting this question. Please show more effort or this thread will also be deleted.

That said, what do you mean "frequency response" in the context of that equation? A frequency response is usually associated with the transfer function of a function block or circuit. Certainly you can sketch the frequency domain version of that time domain function, right? What are the two frequency components of that sketch?
 
Beams of electrons and protons move parallel to each other in the same direction. They ______. a. attract each other. b. repel each other. c. neither attract nor repel. d. the force of attraction or repulsion depends upon the speed of the beams. This is a previous-year-question of CBSE Board 2023. The answer key marks (b) as the right option. I want to know why we are ignoring Coulomb's force?
