    Finding the bandwidth of an FM signal

    Homework Statement 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.] Homework Equations A(t)=A0sin[2πfct+Δfsin(2πfmt)/fm] The...

    What Frequencies Emerge in an AM Signal with Given Parameters?

    Homework Statement Which frequency components are present in the amplitude-modulated (AM) signal A(t)=[1+asin(2πfmt)]A0sin(2πfct), where fm= 3.5 kHz, fc = 540 kHz, and a = 0.1? Homework Equations A(t)=[1+M(t)]A0sin(2πfct), where modulating signal M(t) = sin(2πfm t + ∅), high frequency carrier...
