The even part of a signal x(t) is?(a) x(t)+x(-t)(b) x(t)-x(-t)(c) (1/2

1.	The even part of a signal x(t) is?(a) x(t)+x(-t)(b) x(t)-x(-t)(c) (1/2)(x(t)+x(-t))(d) (1/2)(x(t)-x(-t))I got this question by my college director while I was bunking the class.This interesting question is from Classification of Signals in section DSP – Basic Signaling of Digital Signal Processing
Answer» Correct choice is (C) (1/2)(x(t)+x(-t)) The BEST I can EXPLAIN: Let x(t)=xe(t)+XO(t) =>x(-t)=xe(-t)-xo(-t) By adding the above two EQUATIONS, we get xe(t)=(1/2)(x(t)+x(-t)).
