RESONANT CIRCUITS AS FILTERS Resonant circuits can be made to serve as filters in a manner similar to the action of individual capacitors and inductors. As you know, the series-LC circuit offers minimum opposition to currents that have frequencies at or near the resonant frequency, and maximum opposition to currents of all other frequencies. You […]

Tuned circuits: q relationships in a parallel-resonant circuit, bandwidth, filters, low-pass filter and high-pass filter.
Q Relationships in a Parallel-Resonant Circuit There is no voltage gain in a parallel-resonant circuit because voltage is the same across all parts of a parallel circuit. However, Q helps give us a measure of the current that circulates in the tank. Given: Again, if the Q were 100, the circulating current would be 100 […]

Tuned circuits: how the parallel-lc circuit stores energy, parallel resonance, the characteristics of a typical parallel-resonant circuit, summary of resonance and tuning a band of frequencies.
How the Parallel-LC Circuit Stores Energy A parallel-LC circuit is often called a TANK CIRCUIT because it can store energy much as a tank stores liquid. It has the ability to take energy fed to it from a power source, store this energy alternately in the inductor and capacitor, and produce an output which is […]

Tuned circuits: the ideal series-resonant circuit and how the typical series-lc circuit differs from the ideal.
THE IDEAL SERIES-RESONANT CIRCUIT The ideal series-resonant circuit contains no resistance; it consists of only inductance and capacitance in series with each other and with the source voltage. In this respect, it has the same characteristics of the series circuits you have studied previously. Remember that current is the same in all parts of a […]

Tuned circuits: a.c. Circuits containing both inductive and capacitive reactances, resonant frequency and resonant circuits.
A.c. Circuits Containing Both Inductive and Capacitive Reactances A.c. circuits that contain both an inductor and a capacitor have interesting characteristics because of the opposing effects of L and C. X L and XC may be treated as reactors which are 180 degrees out of phase. As shown in figure 1-2, the vector for XL […]
