Filtre passe bas
Summary
TLDRIn this tutorial video, the instructor demonstrates how to simulate a filter circuit in Proteus version 8, specifically focusing on a low-pass filter with a significant 20 dB attenuation in its bandwidth. The filter is part of a practical exercise, Exercise 4, where circuit simulation is carried out. Users start by setting up a new project called "Filtre Pass 2" and selecting components such as two resistors and one capacitor. The values for R1, R2, and the capacitor are set to 9 kΩ, 1 kΩ, and nanofarads, respectively. The simulation involves creating a schematic in Proteus, adjusting component values, and configuring the circuit to observe the effects of attenuation caused by a resistor in parallel with a capacitor. A sinusoidal input voltage is used, and a frequency domain graph is included to display the gain across different frequencies. This detailed walkthrough helps users understand the impact of component choices on the filter's performance, illustrating the circuit's theoretical underpinnings with its practical output.
