Describe The Boolean expressions for two of the LEDs.

my ending number is 2 Part A (20 marks)Prepare and deliver a five-minute commentary on a topic given below, in which you will record and submit an audio recording as part of your assignment. The commentary should be an audio recording. Tutors will only mark the submitted commentary, they will not mark performances. Note marks are awarded only for the technical content of the commentary, however if the recording cannot be accessed a “0” mark will be given. This means that recordings taken on a mobile phone are acceptable, but please ensure that the commentary is clearly audible before submitting and in a format that is accessible. You should upload to Moodle a word document which contains a link to the audio file, which itself should be uploaded into the cloud using your Microsoft One Drive, and made available for your tutors to access. Part B (20 marks)Describe the process of building the circuit, simulate the circuit in Multisim, include images of the simulation in your report and analyse the experiment. If you do not complete this section you will receive a “0” mark. Please ensure the simulation is saved in a separate file with the question number and appropriate name as part of the file name. This file needs to be included in the Microsoft One Drive folder of which link you copied in Part A, and shared with all the tutors. Part C (50 marks) Answer all questions. You will be required to design and simulate electric circuits using the industry-standard software, Multisim. Please ensure that each different simulation is saved in separate file with the question number and appropriate name as part of the file name. These files need to be included in the Microsoft One Drive folder of which link you copied in Part A, and shared with all the tutors. The report which contains your worked solutions and explanations (including Part A and Part B) SummaryPart A (20 marks)Prepare and deliver a five minute commentary on how the electrons move when a voltage is applied to a P-N junction, and explain how this relates to a diode.Also acknowledge all resources used in the commentary according to CU Harvard referencing style (both the ones that you mention in the commentary and the ones in which you have read and found relevant information). Part B (20 marks)Simulate and represent how to display the voltage discharging curve across the capacitor in a R-C circuit and explain the process behind it in this report with the aid of screenshots and calculations (equations). Your circuit must aim to achieve a time constant based on the second to last digit of your student ID (Table 1). The circuit must be simulated in Multisim.

It has a 230 V variable frequency AC voltage source. Knowing that R1 is 33Ω and the values of R2, C and L are given in Table 2 against the last digit of your student ID: (18 marks) Calculate the following:The resonant frequency (fr) of the circuitThe individual reactances (XL , XC) and the total impedance of the circuit at resonanceThe circuit current and the voltage across each component at resonanceThe power dissipation at resonance and the power factorFor a fixed frequency of 60Hz, recalculate all of the above valuesCalculate the phase angle for the circuit functioning at 60 Hz.What power factor differences can be observed when changing the frequency? How does the phase angle affect the voltage and current?Design the circuit diagram, simulate it in Multisim and verify your results by using plots or snapshots of the simulated circuit values for all the elements (reactances, impedance, current and voltages across the components, power factors). Identify and explain any discrepancies between the results (if any) by means of the appropriately captioned figures. (7 marks)Using Microsoft Excel or similar, plot R (parallel), XL & XC , I, VR (parallel), VC & VL versus frequency (using a range of frequencies from a half of the resonant frequency to twice of the resonant frequency). Explain how these change with frequency.

The Boolean expressions for two of the LEDs are shown below:LED 1= A∙(B+C)+A∙B∙(¯A+¯B+C)LED 2= (¯A∙B+¯B∙A)∙(A+B)Simplify each expression using Boolean algebra. (8 marks)Simulate both the original and simplified logic circuits using Multisim; demonstrate how the results are the same, including the truth tables. (6 marks)Convert the simplified circuit into either NAND or NOR gates ONLY. Justify your choice of logic gates and the advantages of using them in such a circuit. (6 marks)In your report, provide answers to all the questions, include appropriate sketches, tables and diagrams and include screenshots of the simulations with the appropriate captions and in-text citations.
