Circuit And Simulation

File

Simulation files are located at: WaveHarmoney/Circuit_And_Simulation/Simulations/Filters.asc

Filter Type

10 Band Pass Filters (BPFs) were designed with:

• Response: Butterworth, Topology: Multiple Feedback (MFB), Gain (a): 2, Q factor (Q): 4, Capacitor (C): 10nF

Calculations

Component values (R1, R2, R3) were determined via software. Due to unavailability of exact resistor values, closest matches were used.

Simulation Results

Simulations conducted with LTSpice show results for the 10 filters with selected resistors.

PCB

1. Power Supply: Converts AC input to regulated +12V and -12V DC outputs.
2. Filter + LED Driver: Filters input signals and drives LEDs based on the processed signal.

Overview

• Power Supply: Provides stable DC voltage from an AC source.
• Filter + LED Driver: Processes signals to control LEDs.

Usage

1. Power Supply:

   • Connect AC inputs to the designated terminals for DC output.

2. Filter + LED Driver:

   • Connect the signal input to process and drive LEDs.

Enclosure

This project features a Real-Time Audio Spectrum Analyzer with a custom enclosure made from wood and acrylic. Due to the size constraints, 3D printing was not feasible, leading to a combination of materials for durability and aesthetics.

Acrylic Towers

• Materials:
  • Black Acrylic: Forms the outer structure, Transparent Acrylic Cubes: House the LEDs.
• Assembly:
  • 100 transparent acrylic cubes held by a black acrylic outline and cube holder, Assembled with acrylic glue.

LED Configuration

• Choice: Individual LEDs driven by LED driver ICs., Reasoning: Allows precise placement and better visual output compared to LED strips.
