C is the value of the capacitor, expressed in faradsīy substituting the component values in the formula, we have:.L is the inductance value, expressed in henries.The following formula is used to calculate a circuit’s resonant frequency: In this case, the circuit behaves purely resistively, with a minimum modulus and zero phase. The resonant frequency in an RLC circuit is the frequency at which the reactive components of the impedances (inductive and capacitive reactance) are equal and cancel out. The circuit is more sensitive to a single frequency, that of resonance. The newly designed circuit operates in an alternating current regime and behaves differently depending on the frequency of the signal applied to its input. It is a specific kind of band-pass filter. This is a typical tuning circuit that receives a specific radio frequency while rejecting all other frequencies. 10-K input resistance R1: it affects the bandwidth of the circuit and determines the Q factor.Sinusoidal voltage generator V1: its voltage and frequency are not decisive, as it is the simulator that automatically sets these parameters.It is made up of the following components:
It is generated on the PartSim website by dragging electronic components from the proper panels onto the diagram. Tuned circuit simulationįigure 1 illustrates a typical tuned circuit, which is commonly used in radio receivers. This type of analysis is typically used in the design of an amplifier or a filter. In this manner, the frequency responses of the components, particularly the inductive and capacitive ones, can be studied. AC Analysisīy varying the frequency of the input generators, alternating current analysis (AC analysis) can be used to observe the behavior of an electrical or electronic circuit.
In this third article from the PartSim series, we will continue our exploration of the potentials provided by this powerful electronic simulation system. All you need is an internet connection and a browser. PartSim is a web-based app that makes it possible to create and simulate electronic circuits without installing software on your computer.
