Chapter 6, Problem 9HMP
Program Plan Intro
Industrial Supply Company Scenario:
- A data warehouse has to be created by the company where management can gain a single corporate-wide view of critical sales information for identifying best-selling products in specific geographic areas, sales trends as well as key customers.
- The information regarding sales and products are stored in both the divisional sales system that runs on a UNIX server and a corporate sales system that runs on an IBM mainframe.
- The main aim is to create a single standard format, which consolidates these data from both the systems.
Explanation of Solution
Easiness of creating a
- It is ideally easy to create a database with a single standard format. When a new database is constructed, data quality audits and data cleansing must be performed.
- Thee data quality suits and data cleansing can correct any redundancies and inaccuracies in the current systems.
- By using the data cleansing software, the company can combine and integrate the data from all the systems into a single standard format, which is uniform throughout the whole company...
Explanation of Solution
Problem Solving:
- Database specialists help to solve the problems by performing the data quality audits and database cleansing. It also helps to establish an information policy and develop the new database...
Explanation of Solution
Authority to finalize a single company-wide format:
- General business managers have the authority, as they are responsible for the data.
- They have the final power to decide, when managing data resources...

I need help fixing the minor issue where the text isn't in the proper place, and to ensure that the frequency cutoff is at the right place.
My code:
% Define frequency range for the plot
f = logspace(1, 5, 500); % Frequency range from 10 Hz to 100 kHz
w = 2 * pi * f; % Angular frequency
% Parameters for the filters - let's adjust these to get more reasonable cutoffs
R = 1e3; % Resistance in ohms (1 kΩ)
C = 1e-6; % Capacitance in farads (1 μF)
% For bandpass, we need appropriate L value for desired cutoffs
L = 0.1; % Inductance in henries - adjusted for better bandpass response
% Calculate cutoff frequencies first to verify they're in desired range
f_cutoff_RC = 1 / (2 * pi * R * C);
f_resonance = 1 / (2 * pi * sqrt(L * C));
Q_factor = (1/R) * sqrt(L/C);
f_lower_cutoff = f_resonance / (sqrt(1 + 1/(4*Q_factor^2)) + 1/(2*Q_factor));
