Baseband?is a?signal?that has a very narrow frequency range, i.e. a spectral magnitude that is nonzero only for frequencies in the vicinity of the origin (termed?f?= 0) and negligible elsewhere
Answer is:
size of antenna would be huge
Explanation:
need for modulation arises from antenna considerations. If base band signal is to be transmitted then size of antenna would be huge
