웹2024년 8월 21일 · Sorted by: 1. Generating AM has nothing to do with bandpass filters. If you have a carrier frequency of 600 kHz and a modulation frequency of 1.5 kHz, the resultant AM spectrum will consist of signals at 600 kHz, 600 kHz - 1.5 kHz or 598.5 kHz, and 600 kHz + 1.5 kHz or 601.5 kHz.That is the characteristic of all AM signals: the spectrum is the ... 웹2024년 1월 16일 · Difference between baseband and passband signal.

웹2024년 12월 9일 · A signal is said to be band-limited if the amplitude of its spectrum goes to zero for all frequencies beyond some threshold called the cutoff frequency. For one such signal, G (f) in Figure 1, we see that the spectrum is zero for frequencies above α. In that case, the value α is also the bandwidth (BW) for this baseband signal.
