Subject Title
Digital & Broadband Communication Systems

Subject Description
This course builds on foundations established in COM455 to provide practice in the fundamental principles of Digital Signal Processing (DSP). Review of time and frequency domain characteristics of pulse waveforms serves as an introduction to Discrete Time (DT) signals by examining the sampling process, Nyquist criteria and various techniques of Analog-to-Digital Conversion (ADC) and Digital-to-Analog Conversion (DAC). DT correlations and convolutions and their application to communications systems are examined, especially Finite Impulse Response (FIR) and Infinite Impulse Response (IIR) filter design and analysis, including windowing. The application of DT exponential sinusoids enables examination of the Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT). Students make use of MS-Excel©, Agilent VEE©, Matlab© and Simulink© in applying DSP principles to simulated and actual signals. Students emerge with a broad understanding of DSP in communications systems and experience using software tools for DSP design and analysis. Students will also gain valuable insights by working in teams to solve problems, perform research and make presentations on practical DSP applications.

Credit Status
One subject credit in the Electronics Engineering Technology - Communications Option programs.
