JEE Mains 10 December Physics Daily Practice Questions for 2025
Question 1:
A message signal of frequency 5 kHz is used to modulate a carrier signal of frequency 2 MHz. The bandwidth for amplitude modulation is:
(1) 5 kHz
(2) 2.5 kHz
(3) 10 kHz
(4) 20 kHz
Answer: (3)
Explanation: In amplitude modulation, the bandwidth is 2×fm2 times f_m, where fmf_m is the frequency of the message signal.
Bandwidth = 2×5 kHz=10 kHz2 times 5 , text{kHz} = 10 , text{kHz}.
