CTEC5805 - Cyber Engineering - De Montfort University

Learning Outcomes:

1. Design and understanding various components of communication systems

2. Designing and understanding of communication transmitter and receiver

3. Understanding and designing of autonomous network with digital technologies

4. Understanding and designing of medium access techniques with the required specifications

Tasks to be undertaken:

Question 1. Briefly describe each component and step in the design and simulation (using LTSpice) of a single tuning circuit that can receive frequencies of 56MHz, 80MHz and 93MHz.

Question 2. Briefly describe each component and step in the design and simulation (using LTSpice) of a bandpass filter that can pass frequencies from 80MHz to 104MHz. How can you improve the quality and selectivity of a filter?

Question 3. Design and describe an indirect FM modulator to generate an FM carrier with the carrier frequency of 96MHz and frequency deviation of 20KHz. A narrow band FM generator with a carrier frequency of 200KHz and adjustable frequency deviation in the range of 9 to 10 Hz is available. The stock room also has an oscillator with adjustable frequency in the range of 9 to 10MHz. There is a bandpass filter with any centre frequency, and only frequency doublers are available.

Question 4. Briefly describe each step in the design of a CAN communication network for a car that consists of a central unit (ECU) and four monitoring systems (fuel, brake, heating, engine). Use your "P" number as your ECU input identifier. Use a filter and mask to differentiate messages from different monitoring systems and discuss the assigned filter ID and mask ID.

Question 5. Briefly describe each step in the design of a channel access technique for 4 users using TDMA, FHSS and CDMA along with a flow chart.
