Cyber Engineering

Learning outcome 1: Design and understand various components of the communication system

Learning outcome 2: Design and understand the controller area networks for the industrial automation

Learning outcome 3: Understanding and designing of medium access techniques with the required specifications

Question 1. Design and describe the following with details and implement them in LTSpice to validate your design. (Note: Each part will be marked for design, description, LTSpice implementation and result discussion )
a. An LC tunned circuit at 674 KHz
b. A Low Pass Filter to pass frequencies up to 700 KHz
c. A Band Pass Filter to pass a range of frequencies 800KHz - 1700KHz.

d. Amplitude Modulator (AM) and demodulator with a source (1V/5Hz, offset=3V) and carrier (1V/100KHz).

Question 2. Briefly describe each step in the design of a CAN communication network for a car that consists of a central unit (ECU ID = 0x1FF3D89C) and four monitoring systems (fuel (ID=0x13D1100A), brake (ID=0x13D1100B), heating (ID=0x13D1100C), engine (ID=0x13D1100D). Use appropriate filter and mask values to differentiate messages from ECU to monitoring system and from monitoring systems to ECU.

Question 3. A user-A (+449876123456) sends a message (The deadline is tomorrow) to a user-B (+446789123456). First, a user-A converts the message to a PDU format and sends it to AP-1. Then AP-1 sends it to AP-2 over a wireless channel using FHSS with channel switching pattern/sequence of 3102. A maximum of 3 bytes can be sent over each channel in a unit time. User-B converts the message back to text upon receiving it. Describe the following in detail:
a. Text-to-PDU conversion steps at user-A and show the converted PDU characters sequence.
b. Show the process of fragmentation and defragmentation at AP-1 and AP-2 using FHSS and bytes/characters on each channel.
c. PDU-to-Text conversion steps at user -B and show the final received message.
