EE3: Real-Time Digital Signal Processing

Real-Time Digital Signal Processing on a Texas Instruments DSP Starter Kit (TMS320C6713 DSK). Imperial College London Electrical & Electronic Engineering 3^rd year module.

Lab 5: IIR Filtering

Objectives accomplished:

• Learned to design IIR (Infinite-Impulse Response) digital filters using MATLAB.
• Implemented the IIR filter using the C6713 DSK system in real-time.
• Measured the filter characteristics using a spectrum analyzer.

Project: Speech Enhancement through noise reduction

Telephones are increasingly being used in noisy environments such as cars, airports and undergraduate laboratories! The aim of this project is to implement a real-time system that will reduce the background noise in a speech signal while leaving the signal itself intact: this process is called speech enhancement.

~ Paul D. Mitcheson, Imperial College London Dept of EEE, EE3-19 Real Time Digital Signal Processing, 2016

Objectives accomplished:

• Implemented triple buffering: in, processing, and out buffers.
• Implemented various noise estimation and noise reduction techniques,
• Compared their performance and chose parameters that produced the best audible speech enhancement.
