Learning Outcomes
1. Analyse a multi-rate DSP system, in particular, determine the spectral characteristics of signals at different points in the system, and design multi-rate DSP systems to change the sampling rate of a signal by means of an arbitrary rational factor.
2. For discrete-time speech signals, develop DSP algorithms to extract useful features from the signal, in particular energy, zero-crossing count, pitch information, and LPC coefficients, and describe how these features may be used in practical applications like speech recognition
3. Design adaptive filter systems using the LMS algorithm, for use in problems in system identification.
4. Design filters suitable for use in biomedical signal processing applications, in particular removal of narrowband noise.
5. Characterise security threats and outline methods of implementing security
6. Analyse and implement algorithms for encryption, authentication and message integrity
7. Analyse and critique impact and evolution of cloud technologies and data analytics on mobile and web services
8. Analyse and critique the Software Defined Networking paradigm
9. Analyse and advise on networking technologies specifically for financial trading environments
