Question

An audio signal v m =20 sin 2 π(1500 t ) amplitude modulates a carrier vC=80 sin 2 π(100,000 t) The value of percent modulation is (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

% modulation =( Am / Ac ) × 100 % modulation =(20/80) × 100 % modulation =25 %

Q. An audio signal $v_{m} = 20 sin 2 π (1500 t)$ amplitude modulates a carrier $v_{C} = 80 sin 2 π (100, 000 t)$ The value of percent modulation is
