In amplitude modulation, if a message signal of 5 kHz is modulated by a carrier wave of frequency 900 kHz, then the frequencies of the side bands are 2025The heights of tansmitting and receiving antennas are respectively 1 20000 and 1 80000 times the radius of the earth. The maximum distance between these two antennas for satisfacto 2025The layer of the atmosphere that reflects low frequency (LF) electromagnetic waves during day time only is 2025If the ratio of the maximum and minimum amplitudes of an amplitude modulated wave is 7: 3 , then the modulation index is 2025If the maximum and minimum amplitudes of a modulated wave are 25 V and 5 V respectively, then the modulation index is 2025Ionosphere acts as a reflector for the frequency range of 2025If in an amplitude modulated wave, the maximum amplitude is 14 V and the modulation index is 0.4, then the amplitude of the carrier wave is 2025For transmitting a signal of frequency 1000 kHz, the minimum length of the antenna is 2025 Full Communication System list All MHT CET PYQs
