42 Electronic Circuit Analysis Example : 2.3 An amplifier of 40db gain has both its input and output load resistances equal to 600ft If the amplifier input power is - 30db, what is the output power and voltage? Assume that reference power level used is 1 m W in a 600 n resistance. Solution: Since it is logarithmic scale, for dbs, Reference power level = 1 m W. Po (db) = (Pj)db + (gain db); Po = Pj x Ap Output power (Po) = Input Power (P) x Power Gain (Ap) Po = ?Pj = -30db, gain = 40db Po = -30 + 40 = IOdb. 10 log = (1:~)= lOdb Po 10 log 0.001 = 10 Po log 0.001 = 1 Po --=10 0.001 log 10 = 1 . Po = 10 x 0.001 = 10mW (With respect to, 1 m W, the input and output powers are compared and expressed in db) RMS output voltage is, Po 10 log ImW = lOdb) v,2 o R P = o or Vo = ~Po·R =~10xl0-3 x600 = 16 = 2.45 V
