Question

Signals as Vectors:
While deriving Fourier Series for signals we considered signals (functions of time) as
vectors. In vectors, we can measure the length(magnitude) of a vector and distance
between two vectors. When the same notion is extended for signals then,

a. The length of a signal and the distance between two signals cannot be defined
b. The length can be defined but the distance between two signals cannot be
defined
c. Both length and distance can be defined
d. None of the above​
