Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe AM band ranges from about 535 kHz (0.535 MHz) to 1605 kHz (1.605 MHz).
Each station requires 10 kHz of this spectrum.
Although the baseband signal is only 5 kHz.
Additional Information The AM superheterodyne receiver takes the amplitude modulated wave as input and produces the original audio signal as an output.
Selectivity is the ability to select a particular signal while rejecting the others.
Sensitivity is the capacity of detecting RF signal and demodulating it, while at the lowest power level.
Radio amateurs are the initial radio receivers. However, they have drawbacks such as poor sensitivity and selectivity. To overcome these drawbacks, the superheterodyne receiver was invented.
The block diagram of AM receiver is shown in the following figure.
