Carrier amplitude $=$ signal amplitude

Vedclass · Answer

(A) The modulation index $m_a$ is defined as the ratio of the amplitude of the modulating signal $(A_m)$ to the amplitude of the carrier wave $(A_c)$.For cent percent modulation,the modulation index $m_a = 1$ (or $100\%$).$m_a = \frac{A_m}{A_c} = 1 \implies A_m = A_c$.Thus,cent percent modulation is achieved when the amplitude of the modulating signal is equal to the amplitude of the carrier wave.

In $AM$,the cent percent modulation is achieved when
