what is the significance of q factor and bandwidth in RLC series circuit?
Answers
Answer:
BANDWIDTH:
(1) the frequency range of a message or information processing system measured in hertz.
(2) width of the spectral region over which an amplifier (or absorber) has substantial gain (or loss); sometimes represented more specifically as, for example, full width at half maximum.
(3) the property of a control system or component describing the limits of sinusoidal input frequencies to which the system/ component will respond. It is usually measured at the half-power points, which are the upper and lower frequencies at which the output power is reduced by one half. Bandwidth is one measure of the frequency response of a system, i.e., the manner in which it performs when sine waves are applied to the input.
(4) the lowest frequency at which the ratio of the output power to the input power of an optical fiber transmission system decreases by one half (3 dB) compared to the ratio measured at approximately zero modulation frequency of the input optical power source. Since signal distortion in an optical fiber increases with distance in an optical fiber, the bandwidth is also a function of length and is usually given as the bandwidth distance product for the optical fiber in megahertz per kilometer.
(5) width of the band of frequencies between the half power points.
QUALITY FACTOR (Q)
measure of the persistence of damped oscillations in a resonator; 2π times the energy stored in an oscillating system divided by the energy lost in one cycle of the oscillations. Q is a measure of the precision of the frequency selectivity of an electrical resonator or filter. Q is dimensionless.
