If a three stage amplifier has individual stage gains of 10db, 6db and 15db; then the total gain in db is ______

If a three stage amplifier has individual stage gains of 10db, 6db and 15db; then the total gain in db is ______ Correct Answer 31db

The overall gain of a multistage amplifier is given as the product of the gain of the individual stages. Gain (A) = A1 * A2 * A3 ……* An Alternately, if the gain of each stage is given in db The overall gain of the amplifier is the sum of gain of each stage Gain in db = A1 + A2 + A3 (db) = 10+6+15 = 31db.
