請教一下 FM 及 AM 的問題
可否請教一下 FM 及 AM 的問題
1]
A complex waveform (the carrier) with a fundamental frequency of 2k Hz is
amplitude modulated by a sine tone with frequency of 200 Hz, (the
modulator).
Because the carrier is a complex waveform, a sideband pair will be formed
around each of its original partials.
If the partials of the carrier waveform are 2000, 3000, 5000, and 7400 Hz,
what will be the frequencies of the resulting spectrum?
Remember to include the frequencies of the carrier waveform in your answer.
2]
A single tone of 2500 Hz (the carrier) is frequency modulated by a sine tone
(the modulator) of 140 Hz.
Assume that three sideband pairs will be created.
What will be the frequencies of the resulting spectrum?
我不是學 電機 電子 物理 或 類似這些的,故搞不懂
請 不吝指導提示幫忙
謝謝 ^_^
