    Project Assignment: Six-Band Audio LED Visualizer (Complete Implementation)

    You are required to fully design, simulate, implement, and document a Six-Band Audio Level Display System based on analog signal processing principles. The final outcome must be accurate, functional, and professionally presented.

    ## Objective

    Develop a complete system that:

    – Accepts an audio input signal

    – Splits it into six distinct frequency bands

    – Drives six LEDs, each representing a specific frequency range

    – Demonstrates correct behavior through simulation and testing

    ## System Requirements

    ### 1. Circuit Design (MANDATORY)

    Design a complete and correct circuit that includes:

    #### A. Input Stage

    – Audio input (Microphone module or AUX input)

    – Signal conditioning (biasing and amplification if needed)

    #### B. Filter Bank (Core of the system)

    Design six active filters using Op-Amps:

    | Band | Frequency Range |

    |——|—————-|

    | A | 0 60 Hz |

    | B | 60 250 Hz |

    | C | 250 500 Hz |

    | D | 500 Hz 1 kHz |

    | E | 1 2 kHz |

    | F | 2 4 kHz |

    – Use band-pass filters

    – Clearly calculate and justify all resistor and capacitor values

    – Ensure proper separation between bands

    #### C. Detection Stage

    – Convert AC signal to DC using:

    – Rectifier (Diode-based or Precision Rectifier)

    – Smooth the signal using a capacitor

    #### D. Output Stage

    – Each band must drive:

    – One LED

    – With proper current-limiting resistor

    – LEDs must respond to signal strength (brightness or ON/OFF)

    ## 2. Simulation (VERY IMPORTANT)

    You must:

    – Use Proteus or Multisim

    – Draw the full schematic clearly

    – Label all components and values

    ### REQUIRED:

    Record a video showing:

    1. Input signal applied (Function Generator)

    2. Changing frequency step-by-step:

    – 50 Hz

    – 100 Hz

    – 300 Hz

    – 700 Hz

    – 1500 Hz

    – 3000 Hz

    3. Show that:

    – Each LED turns ON only at its corresponding band

    The video must clearly prove that the circuit works correctly.

    ## 3. Testing & Verification

    – Use Function Generator for controlled signals

    – Use Oscilloscope (DSO) with FFT if available

    – Verify:

    – Each band responds to correct frequency

    – No overlapping errors

    – Clean signal behavior

    ## 4. Calculations (MANDATORY)

    Provide:

    – Filter design equations

    – Cutoff frequencies

    – Component selection justification

    – Bode plots (gain vs frequency)

    ## 5. Final Report (Professional)

    Structure:

    ### 1. Introduction

    – Project idea and purpose

    ### 2. Design

    – Block diagram

    – Circuit diagrams

    – Explanation of each stage

    ### 3. Results

    – Simulation screenshots

    – Tables and graphs

    – Observations

    ### 4. Discussion

    – Problems faced

    – Solutions applied

    – Improvements

    ### 5. Conclusion

    – Final system performance

    ## 6. Evidence Required

    – Screenshots of simulation

    – Circuit diagram

    – Video recording of working system

    – Optional: Real hardware photos (if implemented)

    ## Important Notes

    – The circuit must be fully functional and accurate

    – Component values must be calculated, not random

    – Simulation must clearly demonstrate correct band separation

    – Keep the design efficient (minimum components where possible)

    ## Final Deliverables

    1. Complete circuit design (correct and tested)

    2. Simulation file (Proteus/Multisim)

    3. Video showing working circuit

    4. Full report ( 10 pages)

    ## Expectation

    The final system must behave as a real audio spectrum visualizer, where each LED accurately represents its assigned frequency band.

    Introduction
    This assessment builds on your initial care coordination infographic by providing an opportunity to research the literature and apply evidence to support what communication, teaching, and learning best practices are needed for your selected healthcare problem.

    Note: You are required to complete this assessment only after Assessments 2, 3, and 4 are successfully completed and you have permission from faculty to move forward.

    Professional Context
    Care coordination is the process of providing a smooth and seamless transition of care as part of the health continuum. Nurses must be aware of community resources, ethical considerations, policy issues, cultural norms, safety, and the physiological needs of patients. Nurses play a key role in providing the necessary knowledge and communication to ensure seamless transitions of care. They draw upon evidence-based practices to promote health and disease prevention to create a safe environment conducive to improving and maintaining the health of individuals, families, or aggregates within a community. When provided with a plan and the resources to achieve and maintain optimal health, patients benefit from a safe environment conducive to healing and a better quality of life.

    Please watch the following brief video message for an overview of what to keep in mind as you complete your Care Coordination Strategy.

    Final Care Coordination Strategy.
    Preparation
    You are encouraged to complete the Vila Health: Cultural Competence activity prior to completing this assessment. Completing course activities before submitting your first attempt has been shown to make the difference between basic and proficient assessment.

    In this assessment, you will evaluate the preliminary care coordination infographic you developed in Assessment 2 using best practices found in the literature.

    To prepare for your assessment, you will research the literature on your selected healthcare problem. You will describe the priorities that a care coordinator would establish when discussing the plan with a patient and family members. You will identify changes to the strategy based upon evidence-based practice and discuss how the strategy includes elements of Healthy People 2030.

    Instructions

    Build on your preliminary care infographic and selected health concern and population and create a detailed comprehensive final care coordination strategy.

    It is suggested that you use the following outline to organize your 57 page paper, including Level 1 and 2 section headings:
