(a) For each of the signals given, determine mathematically whether the signal is even, odd, or neither.


(i) x[n] = 2


(ii) x[n] = 2u[n]


(iii) x[n] = (2)|n|


(iv) x[n] = 5 + 0.9n + 0.9–n


(v) x[n] = cos(0.1n)


(vi) x[n] = cos(0.1nπ/6)

(b) Sketch the signals and verify the results of Part (a).


(c) Find the even part and the odd part of each of the signals.
