A speech signal of 3 kHz is used to modulate a crrier signal of frequency ! MHz, using amplitude modulation. What will be the frequencies of side bands ? |
1.003 MHz - 0.997 MHz 3001 kHz - 2997 kHz 1003 kHz - 1000 kHz 1 MHz - 0.997 MHz |
1.003 MHz - 0.997 MHz |
\(\nu\) = 1 MHz ; \(\Delta \nu\) = 3 kHz = 0.003 MHz Side bands = \(\nu\) \(\pm \) \(\Delta \nu\) = 1.003 MHz, 0.997 MHz |
