According to a study1 , “the main melody (spectral/pitch information) is most often carried by the highest-pitched voice, and the rhythm (temporal foundation) is most often laid down by the lowest-pitched voice.” In particular, the study used neural recordings to show that rhythmic timing information is carried in lower-pitched sound sources. In order to test this notion, you need to design a filter to cut the high-frequency components of a provided song recording that has strong beat. The desired specifications for the design is a Butterworth filter operating at 44,100 Hz sampling rate, with a stopband attenuation of 45 dB at 1,000 Hz and at least -0.9 dB passband edge at 500 Hz. 1. What type of filter (e.g., lowpass, highpass) do you need to design? Explain your reasoning. 2. (a) Design a continuous-time (CT) Butterworth filter to meet the specifications by providing the order and cutoff frequency of the filter (passband specifications must remain fixed); provide all computation steps. (b) Use Matlab to design the CT Butterworth filter; provide the plot of the magnitude response |H(jΩ)| and your Matlab code. (relevant Matlab functions: buttord.m, butter.m, freqs.m) 3. (a) Use the impulse invariance method to obtain the discrete-time (DT) design from the CT design; provide the DT filter specifications. (b) Use Matlab to design the DT Butterworth filter; provide the plot of the magnitude response |H(e jω)| and your Matlab code. (relevant functions: impinvar.m, freqz.m) 4. Repeat 3(a) and (b) using the bilinear transformation method. (relevant functions: bilinear.m, freqz) 5. Load the data in Matlab using load shake your bootay data.mat. Filter the data using the Matlab command filter.m, and name the filtered data data out. Use sound(data,fs) and sound(data out,fs), with sampling frequency fs, to send the original and filtered data to your PC speaker. Provide time-frequency transformation plots of the original and filtered data (see sample code below) and discuss the effect of the filter on the filtered data. I HAVE ATTACHED THE QUESTION IN THE ATTACHMENTS.

CYB 220 Project Two Guidelines and Rubric Overview One of the projects for this course is the creation of a network segmentation strategy in which you will create host-based and network-based firewall policies in a provided network and explain how the network achieves isolation, segmentation, and least privilege. As a security analyst, you will often be asked to evaluate and suggest solutions that require this type of network security design, so this project demonstrates competency in the field. The audience for this strategy is your IT security manager. The project leverages the skills that you have built in Module Four. The project will be submitted in Module Six. In this assignment, you will demonstrate your mastery of the following course competency:  CYB-220-03: Describe the fundamental principles and practices of network traffic flow policy and enforcement Scenario As a security analyst, you are tasked with creating a network segmentation strategy for your IT security manager. This includes configuration tasks in a network as well as a written rationale of the network segmentation strategy. Your instructor will post a real-world scenario that includes the minimum specifications on which your work will be based. You will also be provided with a Packet Tracer native file (.pkt) that you will import into the Packet Tracer application to use as the base diagram for your network. You will use the scenario and the provided Packet Tracer lab environment to do your work. Prompt You must address the critical elements listed below. The codes shown in brackets indicate the course competency to which each critical element is aligned. Network Segmentation Strategy I. Configuration A. Configure the host-based firewall policy to meet project specifications. Provide a screenshot of the configured policy. [CYB-220-03] B. Configure the FTP server to meet project specifications for access control. Provide a screenshot of the configured FTP server. [CYB-220-03] C. Configure the network-based firewall policy to meet project specifications for the extended access control list. Provide a screenshot of the configured policy. [CYB-220-03] 2 II. Rationale A. Describe how network segmentation is achieved after meeting the configuration requirements for the host-based firewall. [CYB-220-03] B. Describe how the concept of least privilege is achieved in the configuration of the FTP server. [CYB-220-03] C. Describe an approach of employing a network-based firewall to achieve network isolation to meet project specifications. [CYB-220-03] Project Two Rubric Guidelines for Submission: Your submission should be 1 to 2 pages in length (not including screenshots) and should be written in APA format. Use double spacing, 12-point Times New Roman font, and one-inch margins. Use a filename that includes the course code, the assignment title, and your name—for example, CYB_100_Project_One_Neo_Anderson.docx.

CEC220 FINAL PROJECT (Digital circuits)Engine Controller Design In this project, you will have to design a complete four-strokefour-cylinder engine controller in VHDL. This controller willwork under the assumption of having an electronically drivenvalvetrain and input from a crank position sensor.A typical four-stroke engine has four “states”, called strokes :intake, compression, power, and exhaust. These four strokesoccur over two revolutions of the crankshaft, with each stroketaking half a revolution. The operation of a single cylinder isillustrated in the figure below (components marked in red areengaged):
