A single tone FM single is given by $V_{FM}$ (t) =10 sin(16 π x ${10}^6$ t +20 sin 2 π x $10^3$ t)

Comparing the given equation with the standard expression for FM we get,

$m_f$ =20

1. $f_m$ = 1kHz

2. Deviation ς =20kHz

3. $f_c$ = 8 MHz

4. P= ${(10/√(2) )}.^2$ / R =50/R watt

5. BW =2 [ς + $f_m$ ]= 42 kHz
