Definitions [1]
A signal of 5 kHz frequency is amplitude modulated on a carrier wave of frequency 2 MHz. The frequencies of the resultant signal are ______.
A signal of 5 kHz frequency is amplitude modulated on a carrier wave of frequency 2 MHz. The frequencies of the resultant signal are 2005 kHz, 2000 kHz and 1995 kHz.
Explanation:
Amplitude modulated wave consists of three frequencies are ωc + ωm, ω, ωc - ωm
i.e. 2005 kHz, 2000 kHz and 1995 kHz.
