Question

Consider a parallel resonant LC circuit with L=2.5 mH and the capacitance of the variable capacitor given as C(t)=10μF−5×10−7m(t), where m(t) is the message signal which varies slowly with max|m(t)|<<1. What is the approximate carrier frequency of the resulting frequency modulated signal xc(t) 0.25 kHz 2 MHz 2.5 kHz 1.0 kHz
