B refers to Basic, A refers to Average, H refers to Hard, and * refers to problems with answers.

(A) Find the 3 dB and 6 dB bandwidths of the signal shown in Figure. The signal XdB bandwidth is defined as BWxdB = fH,xdB − fL,xdB where fH,xdB is the signal’s higher frequency, at which the signal power is XdB lower than the signal’s largest power; and, fL,xdB is the signal’s lower frequency, at which the signal’s power is XdB lower than the signal’s largest power.

FIGURE Signals in the frequency domain for Problem.
