Flashcards on Resonant Circuits
Click on the flashcard to see the answer
What is a Resonant Circuit?
A circuit which can store electrical energy in the form of oscillations at its natural frequency.
What is Natural Frequency?
The frequency at which an object vibrates when disturbed with no external force.
What is Resonance Frequency?
The specific frequency at which energy is absorbed by the circuit.
What is Q Factor?
A measure of how selective a resonant circuit is. It is the ratio of the energy stored in the circuit to the energy lost per cycle.
What is Tuned Frequency?
The specific frequency at which the resonant circuit is designed to operate.
What is Active Filter?
A circuit that uses active components (transistors or op-amps) to provide amplification and filtering.
What is Passive Filter?
A circuit that uses only passive components (resistors, capacitors, inductors) to provide filtering.
What is Bandwidth?
The range of frequencies between the upper and lower cut-offs of a filter.
What is Quality Factor?
A measure of the damping of a resonant circuit. It is the ratio of the energy stored in the circuit to the energy lost per cycle.
What is a Tank Circuit?
A resonant circuit consisting of an inductor and a capacitor connected in parallel.
What is a Series Resonant Circuit?
A resonant circuit consisting of an inductor and a capacitor connected in series.
What is Parallel Resonance?
A resonant condition that occurs in an LC circuit when the capacitive and inductive reactances are equal in magnitude and cancel each other out.
What is Series Resonance?
A resonant condition that occurs in an LC circuit when the capacitive and inductive reactances are equal in magnitude and add up to a large value.
What is Anti-Resonance?
A condition in a series resonant circuit where the impedance is at a maximum, causing the current flow to be minimized.
What is Over-Coupled Circuit?
A resonant circuit in which the mutual inductance between the inductor and the coil is strong, leading to a high Q factor and narrow bandwidth.
