    – 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)

    | A | 0 60 Hz |

    | B | 60 250 Hz |

    | C | 250 500 Hz |

    | D | 500 Hz 1 kHz |

    – 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:

  • week 5 several non professional

    Several non-professional behaviors are plaguing the nursing profession such as bullying and incivility. This week we are exploring non-interprofessional behaviors, the ethic-of-care, and the ethic-of-justice.

    How do you think non-interprofessional behaviors affect the ethic-of-care and ethic-of-justice frameworks? Which framework or work culture do you see predominantly in your work environment? In addition, critically appraise effective strategies for DNP-prepared nursing role development from an ethic-of-care perspective. How could you alter your nursing practice as a result of completing your DNP program to improve the ethics of your practice?

    For this week, when you are reflecting on this discussion thread, consider professional ethics as regards the patient and beyond the patient. The Code of Ethics for Nurses addresses other professional concepts that point the way to expected professional behaviors. How can these help you with your practice and the practice behavior of other nurses?
