WebModulation is a process of varying one or more properties of a carrier signal (High-frequency signal) with a modulating signal (Low-frequency signal). Need for Modulation: 1. It is needed in order to match the characteristics of the input signal to that of channel characteristics. 2. Multiplexing is made possible due to modulation. 3. WebIn other words, the baseband-change-to-carrier-amplitude-change relationship is fixed. We cannot, for example, design the system such that a small change in the baseband value will create a large change in the carrier amplitude. To address this limitation, we introduce m, known as the modulation index. $$ x_{AM}(t)=\sin(\omega_Ct)(1+mx_{BB}(t))$$
