Question
If the highest frequency component of message signal is $15 \mathrm{kHz}$ and this AM modulates a carrier signal of $500 \mathrm{kHz}$, what is the minimum bandwidth of a filter centered at the carrier frequency that will transmit the signal?

For an FM modulator with a peak frequency deviation Δf = 10kHz, a modulating signal frequency fm= 10kHz, Vc =10V and 500kHz carrier, determine 1. Actual minimum bandwidth from the Bessel function table 2. Approximate minimum bandwidth using Carson's rule 3. Plot the output freq spectrum for the Bessel approximation
Each AM radio signal has components rang. ing from $10 \mathrm{kHz}$ below its carrier frequency to $10 \mathrm{kHz}$ above its carrier frequency, Various radio stations in a given gcographical region are assigned different carrier frequenciesso that the frequency ranges of the signals do not overlap. Suppose that a certain AM radio transmitter has a carrier frequency of $980 \mathrm{kHz}$. What type of filter should be used if we want the filter to pass the components from this transmitter and reject the components of all other transmitters? What are the best values for the cutoff frequencies?
