Consider the noncoherent receiver consists of two paths; the band-pass filter in the top path is tuned to the carrier frequency representing symbol 1, and the band-pass filter in the lower path is tuned to the alternative carrier frequency representing symbol 0. These two filters are followed by a pair of energy-level detectors, whose outputs are applied to the comparator to recover the original binary data stream.

Similarly, the noncoherent BFSK receiver is twice as complex as the noncoherent BASK receiver. What would be the advantage of the BFSK system over the BASK system, given that they operate on the same binary data stream and the same communication channel? Justify your answer.
