Question

A signal wave of frequency 12 kHz is modulated with a carrier wave of frequency 2.51 MHz. The upper and lower side band frequencies are respectively, 2512 kHz and 2508 kHz, 2522 kHz and 2488 kHz, 2522 kHz and 2498 kHz, 2512 kHz and 2488 kHz

MARKS App · Accepted Answer

Upper side band (USB) frequency = f c + f m = 2.51 M H z + 12 k H z = 2510 + 12 k H z = 2522 k H z Lower side band (LSB) frequency = f c - f m = 2.51 M H z - 12 k H z = 2510 - 12 k H z = 2498 k H z
