WebJun 8, 2024 · where k f is called as the frequency sensitivity of the modulator. Varactor Diode Modulator. The varactor diode FM modulator has been shown below in figure 3. Fig.3 : Varactor Diode Modulator. A varactor diode is a semiconductor diode whose junction capacitance varies linearly with the applied bias andThe varactor diode must be reverse … WebThe FM waveform is generated by applying the formula given above. The integral of sin (x) is –cos (x) + C. The constant C is not relevant here, so we can use the following equation to compute the FM signal: xF M (t) = sin((10 × 106 × 2πt)− cos(1 × 106 × 2πt)) x F M ( t) = sin ( ( 10 × 10 6 × 2 π t) − cos ( 1 × 10 6 × 2 π t))
