Using the Laplace transform as part of your circuit analysis provides you with a prediction of circuit response. Analyze the poles of the Laplace transform to get a general idea of output behavior. Real poles, for instance, indicate exponential output behavior.Follow these basic steps to analyze a circuit using Laplace techniques: Develop the differential equation in the time-domain using Kirchhoff’s laws and element equations.

There are many applications for an RLC circuit, including band-pass filters, band-reject filters, and low-/high-pass filters. You can use series and parallel RLC circuits to create band-pass and band-reject filters. An RLC circuit has a resistor, inductor, and capacitor connected in series or in parallel.You can get a transfer function for a band-pass filter with a parallel RLC circuit, like the one shown here.

RLC series band-pass filter (BPF) You can get a band-pass filter with a series RLC circuit by measuring the voltage across the resistor VR(s) driven by a source VS(s).

A first-order RL parallel circuit has one resistor (or network of resistors) and a single inductor. First-order circuits can be analyzed using first-order differential equations. By analyzing a first-order circuit, you can understand its timing and delays.Analyzing such a parallel RL circuit, like the one shown here, follows the same process as analyzing an RC series circuit.

To find the total response of an RL parallel circuit such as the one shown here, you need to find the zero-input response and the zero-state response and then add them together.After fiddling with the math, you determine that the zero-input response of the sample circuit is this:Now you are ready to calculate the zero-state response for the circuit.

When doing circuit analysis, you need to know some essential laws, electrical quantities, relationships, and theorems.Ohm’s law is a key device equation that relates current, voltage, and resistance. Using Kirchhoff’s laws, you can simplify a network of resistors using a single equivalent resistor. You can also do the same type of calculation to obtain the equivalent capacitance and inductance for a network of capacitors or inductors.

In circuits, inductors resist instantaneous changes in current and store magnetic energy. Inductors are electromagnetic devices that find heavy use in radiofrequency (RF) circuits. They serve as RF “chokes,” blocking high-frequency signals. This application of inductor circuits is called filtering. Electronic filters select or block whichever frequencies the user chooses.
