3/22/2023 0 Comments Q ifactor n series addTo transform a low pass filter to a high pass filter, the numerator of the low pass filter’s transfer function is changed to. Where E is the applied voltage, is the capacitor voltage, is the inductor voltage, is the inductive reactance, is the capacitive reactance, R is the coil resistance and I is the circuit current. The Q-meter works based on the characteristics of the resistance, inductance, and capacitance of the resonant series circuit.Īs we discussed, every Q meter works on the principle of a series resonance. They cause energy that oscillates between the electrical and the magnetic fields of the capacitor and the inductor. Resonance is the state that occurs in the circuit when their inductance and capacitance are of equal magnitude. The Q meter operates on the principle of series resonance. The Q metre is used in a laboratory to measure the radio frequency of the coils. It also describes the characteristics of the coil and the capacitor. The Q metre calculates the quality factor of the circuit and indicates the total energy dissipated by the circuit. The instrument used to calculate the quality factor of the radio frequency circuit is called the Q-meter. He used since all the other letters of the alphabet were taken. Curiously, his option of letter Q was made not because of the word quality factor. During his studies, he developed the idea of the Q factor. He measured the efficiency and consistency of the various coils. Department of Engineering of the Western Electric Company. The definition of Quality Factor was originally envisaged by an engineer called K. The quality factor measures the performance of a coil, a capacitor, or an inductor in terms of its losses and resonator bandwidth. Q factor (also known as Quality Factor or Q-factor) is defined as a dimensionless parameter that describes the underdamped condition of an oscillator or resonator.
