Generation ofwide-band FM can be done by variousmeans.However, only themost common and conceptually the simplest one, known as the direct method, is considered here. It employs a voltage-controlled oscillator (VCO) as a modulator. A VCO is an oscillator whose oscillation frequency is equal to the resonant frequency of a tuned circuit, as shown in Figure. The frequency can be varied if either the inductance or the capacitance is made voltage-sensitive to the message signal f (t).
Determine i L (t) and v C (t) for t> 0 in the circuit given in Figure.
The resistance of an electrical conductor depends on 4 factors, these being: a) The length of the conductor b) The cross-sectional area of the conductor
Magnetic circuits To see how this is used in practice, consider a coil of N turns wound onto a closed ring shaped former with a very high (note: r (steel) = 200
