Although almost all communication signals are now processed digitally, the transmission and reception of these is an analogue process whether this is wireless, wired, or optical. This course covers the analogue and digital circuits required to generate and detect the transmitted signals and transform these into useful information. The course will discuss the major blocks in a communication system and examine the specification and detailed circuit implementation of some of these blocks.

This course will be timetabled in blocks, typically one week in four.

Due to the team based nature of the coursework and laboratories, it is not possible to reassess the laboratory practical or laboratory project work.

The aims of this course is to provide students with an appreciation and understanding of the requirements, specification, and design of circuits used in communications systems. After explaining and analysing the system and application demands of communication systems incorporating wired, wireless, and optical technologies, the course introduces the analytical tools required for the rigorous treatment of design problems related to communications. Starting at block level, the course progresses through sub-block and circuit level specification and design giving students experience in the practical implementation of mixed signals communications circuits. In a mixed signal context, the course includes discussion and analysis of ADC and DAC components intended to interface into DSP baseband processing.

By the end of this course students will be able to:

■ illustrate the key blocks in a communications system and evaluate the impact of the channel on system performance

■ illustrate the operational characteristics of common semiconductor devices used in communications and apply their simplified standard models to circuit analyses and simulation

■ analyse circuits used for modulation and demodulation in typical communication systems

■ demonstrate the operation of a phase-locked loop (PLL) and its applications in communication systems

■ analyse and design standard circuits based on transistor amplifiers, integrated circuit blocks, and/or a PLL to meet a given application

■ illustrate the operation of standard analog-to-digital and digital-to-analog converters and select an appropriate architecture for a given application

■ assess the stability of a circuit as a function of frequency and jitter
