An AM radio station broadcasts music with an absolute bandwidth of 5 kHz. The station uses double-sideband, transmitted-carrier modulation and its carrier frequency is 1 MHz.
(a) What are the minimum and maximum frequency limits 
of the bandwidth in positive frequency space occupied by the modulated carrier that is broadcast by this station?
(b) If the carrier frequency is changed to 1.5 MHz, what are the new minimum and maximum frequency limits 
of the bandwidth in positive frequency space occupied by the modulated carrier that is broadcast by this station?
(c) If the station changed to single-sideband suppressed-carrier modulation, broadcasting the upper sideband only (in positive frequency space) and the carrier frequency were the original 1 MHz, what are the new minimum and maximum frequency limits 
of the bandwidth in positive frequency space occupied by the modulated carrier that is broadcast by this station?
(a) What are the minimum and maximum frequency limits, 
of the bandwidth in positive frequency space occupied by the modulated carrier that is broadcast by this station?
= 0.995 MHz
= 1.005 MHz
(b) If the carrier frequency is changed to 1.5 MHz, what are the new minimum and maximum frequency limits, 
of the bandwidth in positive frequency space occupied by the modulated carrier that is broadcast by this station?
= 1.495 MHz
= 1.505 MHz
(c) If the station changed to single-sideband suppressed-carrier modulation, broadcasting the upper sideband only (in positive frequency space) and the carrier frequency were the original 1 MHz, what are the new minimum and maximum frequency limits,
of the bandwidth in positive frequency space occupied by the modulated carrier that is broadcast by this station?
= 1 MHz
= 1.005 MHz
