In amplitude modulation, carrier wave frequencies are:
An audio signal represented as 25 sin 2pi ( 2000 t) amplitude modulated by a carrier wave : 60 sin 2pi (100,000)t . The modulation index of the modulated signal is
An audio signal v_m = 20 sin 2 pi (1500 t) amplitude modulates a carrier v_C = 80 sin 2pi (100,000t ) . The value of percent modulation is ___
In an amplitude modulator circuit, the carrier wave is given by, C(t)=4sin (20000pit) while modulating signal is given by, m(t)=2 sin (2000pit) . . The values of modulation index and lower side band frequency are:
In an amplitude modulator circuit the carrier wave is given by C(t) = 4 sin(2 pi × 10^7 t) while modulating signal is given by m(t) = 2 sin(2 pi × 10^5 t) . Then the bandwidth of the broadcast signal will be
If the maximum amplitude of an amoplitude modulated wave is 25 V and the minimum amplitude is 5V, the modulation index is
An audio signal of amplitude 0.1 V is used is used in amplitude modulation of a carrier wave of amplitude 0.2 V. Calculate the modulation index.
What is total modulation index when a carrier wave is modulated by a number of sine waves having modulation index mu_1, mu_2, mu_3, …….mu_n ?
Modulation voltage and carrier voltage of a wave is 12 and 4. Find modulation index
A wave is represented as e=10 sin (10^(8)t+6 sin 1250t) then the modulating index is
