A source produces symbols A, B, and C having probabilities P[A] = 0.9, P[B] = 0.07, P[C] = 0.02, P[D] = 0.01. The source entropy equals _____ (x.xx) bits/symbol.
Fill in the blank(s) with the appropriate word(s).
HS = -? P[Xi] log2 P[Xi] = -(0.9)(-0.15) –(0.07)(-3.84) –(0.02)(-5.64) –(0.01)(-6.64) = 0.583 bits/symbol
