Filtre passe Bande
Ringkasan
TLDRLa vidéo explique comment concevoir et simuler un filtre passe-bande en utilisant une résistance, une inductance (bobine) et un condensateur. Le processus implique de connecter ces composants de manière spécifique, puis de déterminer la fréquence centrale du filtre, qui est d'environ 15,7 kHz, par simulation. Les fréquences F1 et F2 aident à calculer la largeur de bande passante du filtre. La simulation montre que les signaux à la fréquence centrale passent sans atténuation, validant le fonctionnement du filtre. Des outils comme l'oscilloscope sont utilisés pour illustrer cela en visualisant la tension d'entrée et de sortie.

In this segment, the focus is on designing a band-pass filter using three components: a resistor, an inductor (inductance L1), and a capacitor in parallel with the inductor. The components are connected in a specific manner. The inductor value is 100 nano, the resistor value is 100 Ohms, and a sinusoidal input voltage of 0.5 Hz is applied. The gain versus frequency graph is plotted, and simulation is run. The central frequency is around 15.7 kHz, and -3 dB bandwidth is calculated by finding F1 and F2, around 9.84 kHz and 28.8 kHz respectively, demonstrating the filter's functionality. By simulating with an out-of-pass band frequency (100 Hz), no output is observed, validating the filter's operation.

What components are needed for the band-pass filter?
You need a resistor, an inductor, and a capacitor.
What is the purpose of the band-pass filter?
It allows signals within a certain frequency range to pass while attenuating frequencies outside that range.
How is the central frequency of the filter determined?
It's determined through simulation and is highlighted as approximately 15.7 kHz.
What are F1 and F2 in the filter design?
F1 and F2 are frequencies used to determine the filter's bandwidth.
What happens when a signal is outside the passband?
The signal is highly attenuated, resulting in no visible output.
What simulation tools are used in the process?
An oscilloscope and simulation software are used to display and calculate frequencies and voltages.
How does the filter validate its function?
By showing that a signal within the center frequency passes through unaffected, while signals outside are attenuated.
