1. The problem statement, all variables and given/known data Consider the frequency-modulated (FM) signa A(t)=A0sin[2πfct+Δfsin(2πfmt)/fm] , where fc = 3.5 kHz, fm = 88.1 MHz. What is the bandwidth of the signal? [Note: You may take sin≅ and cos≅1 for x (in radian) << 1.] 2. Relevant equations A(t)=A0sin[2πfct+Δfsin(2πfmt)/fm] 3. The attempt at a solution for finding bandwidth, isn't it (fc+fm)-(fc-fm)?
