    Study Notes

    Multiple-Feedback Band-Pass Filter

    • A multiple-feedback band-pass filter has two feedback paths through R2 and C1.
    • R1 and C1 provide a low-pass response, while R2 and C2 provide a high-pass response.
    • The maximum gain, A0, occurs at the center frequency.
    • Typically, Q values are less than 10 in this type of filter.

    Project Breakdown and Scheduling

    • Projects can be broken down into tasks that should take about a week or two to complete.
    • Bar charts are commonly used to represent project schedules.
    • Task duration, effort, and dependencies should be considered when creating a project schedule.

    Estimation Techniques

    • There are two types of estimation techniques: experience-based and algorithmic cost modeling.
    • Experience-based techniques rely on a manager's experience of past projects and the application domain.
    • Algorithmic cost modeling uses a formulaic approach to compute project effort based on product attributes.

    Cost Estimate Uncertainty and Contractual Terms

    • Organizations may increase their price by a contingency to account for cost estimate uncertainty.
    • Contractual terms can affect the price charged, such as retaining ownership of the source code.

    Project Plan Sections

    • A project plan typically includes sections such as introduction, project organization, risk analysis, and hardware and software resource requirements.
    • The work breakdown section sets out the project activities, inputs, and outputs.
    • The project schedule shows dependencies between activities, estimated times, and resource allocation.

    Software Pricing

    • Software pricing estimates consider hardware, software, travel, training, and effort costs.
    • There is no simple relationship between development cost and price charged to the customer.
    • Broader organizational, economic, political, and business considerations influence the price charged.

    Factors Affecting Software Pricing

    • Requirements volatility, financial health, and market opportunity are factors that affect software pricing.
    • Organizations may lower their price due to requirements volatility, financial difficulties, or to gain market opportunity.
    • Cash flow is more important than profit in difficult economic times.
