The discussion centers on the frequency spectrum of a DSB-SC signal, with participants confirming and correcting calculations. A potential typo was identified, suggesting that the frequency should be 5000 instead of 500 in the equation for S(f). Clarifications were made regarding the absence of carrier power in the DSB-SC spectrum, emphasizing that only sidebands exist at frequencies above and below the carrier. The mathematical relationship between the modulated signal and its spectrum was highlighted, reinforcing the understanding of DSB-SC characteristics. Overall, the conversation focuses on ensuring accuracy in the frequency representation of the DSB-SC signal.
