Hi dszabo,You're correct. I did not remember what the Fourier transform is doing for a time domain signal with odd symmetry (sine), even symmetry (cosine), and...

Hi Kaz,Thank you for your answer. Your concept of asymmetric spectrum can be generated by using single-sideband modulation for two different signals. Signal A...

Hi Rick Lyons,First of all, your tutorials are the inspiration for me to draw these similar looking diagrams above. I enjoy your graphics and derivations very much....

Hi dszabo,Thank you for your answer. I believe you may have unlocked the concept in my head regarding the fact that an asymmetric signal can be made from the sum...

Hi kaz,Thank you for responding to my question. Perhaps my question may be better explained with the illustration I have inserted here. I understand that i(t) &...

Hi fred_harris,Thank you for replying. I think my problem is better depicted if I create a diagram such as the one inserted here. In your explanation, the amplitude...
