oops.. :) but still, S1 and V1 are similar in phase, aren't they? And since that's the case, S/V yields magnitude only (on the real axis). Same for both loads. And since the phase becomes 0 for both I1 and I2 (which is wrong obviously, but I cannot figure out where exactly I miss a thing here)...

Attached. I'll be happy for some help here. Thanks. :redface:

:-p thanks.

I understand that the original formula represents a multiplication of two signals, x(t) (better called x_{m}(t) , just for a better distinction) and x_{c}(t) . I also agree that using a trigonometric relation could transform that multiplication and represent it as a sum of two signals. Applying...

You say 0.5\pi corresponds to \omega_{m} because the given x(t) is the message signal and therefore the \omega_{m}? How can you actually know there's no product in the carrier frequency? Another question is if I can be sure the frequency range of \omega_{c} is...

My problem is how to continue from here and to use the given x(t)=4sin(0.5πt) to find what I need to. I just cannot see it yet..

A signal, x(t)=4sin(0.5\pi t), is transmitted by a DSB modulator. What is the frequency range of the carrier wave corresponding to the given message (data) signal? My basic misunderstanding here is if the given signal is the message signal that I should demodulate from a DSB modulated...

Hello. I have problem approaching the attached question and understanding how to solve it. I desperately need some help here. :confused: Thanks! :smile:

Thanks a lot! you've really helped me :smile:

Hi. I receive an error message once simulating in PSPICE. I have attached a file that explains the problem in details. Will be glad to know the source of the problem. Thanks! :redface:

Hi. I have a question about and IID process (attached). I'll be happy if someone could help me understnad it better. Thanks in advance :shy:

Actually I'm quite satisfied with knowing the same result could also be received using contour integration. The real idea here is to use the Fourier transform's properties (since that's the subject I'm focused on now, really), so no need to deviate from that right now (thanks a lot though...

Thanks, but I'm still unable to really figure it out I made the computation (file attached), and still have some differences in the results I get, so I probably miss something here... but what exactly?

Hello. I have a problem convolving two functions. I have attached a file with the problem in details, and will be very grateful if someone can provide me with a proper explanation. Thanks! :shy:

attached in a file. I will be grateful for some help here. Thanks :smile:
