Question
Objective: Use a drawing to show the setup in Multisim that can simulate two cascaded filters: an L-Type High-Pass Filter followed by a Pi-Type Band-Stop Filter.
Circuit Details
-
L-Type High-Pass Filter
- Cutoff frequency: 666.67 Hz
- Components:
- Capacitor: 56.99 µF (in series with input)
- Inductor: 1 mH (parallel to load)
- Load: 3000 Ω
- Function: Allows frequencies above 666.67 Hz to pass.
-
Pi-Type Band-Stop Filter
- Block frequency range: 1000 Hz to 1333.33 Hz
- Components:
- Capacitors: Two 18.61 µF (one on each side of inductor)
- Inductor: 1 mH (between capacitors, parallel to load)
- Load: 3000 Ω
- Function: Blocks frequencies between 1000 Hz and 1333.33 Hz.
Combined Setup
- Step 1: Set up the L-Type High-Pass Filter.
- Step 2: Connect the Pi-Type Band-Stop Filter in series after the high-pass filter.
- Expected Result: The cascaded filters should pass harmonics above 666.67 Hz while blocking those between 1000 Hz and 1333.33 Hz, allowing frequencies beyond that range to reach the load.
