Challenge Problems
Push your limits with challenges.
Question 1
Given an amplitude modulation system with a carrier frequency of 1 MHz and a modulating signal with a maximum frequency of 5 kHz, calculate the total bandwidth required.
💡 Hint: Remember the formula for bandwidth in AM is double the maximum frequency of the modulating signal.
Question 2
For a frequency modulation system with a peak frequency deviation of 75 kHz and modulation index of 5, apply Carson's rule to find the bandwidth.
💡 Hint: Make sure to closely examine how to apply Carson's rule, and keep track of peak deviation and modulating frequency.
