An audio signal of amplitude 
and frequency 
is to be transmitted using a carrier wave of amplitude 
and frequency 
. Either amplitude modulation or frequency modulation may be used. The amplitude modulation is at a rate of 
. The frequency modulation is at a rate of 
. Complete the table below to show the maximum and minimum values of the amplitude and of the frequency of the modulated wave for each type of modulation.
For the amplitude modulated wave in (a), determine the bandwidth.
