Assignment Description: The purpose of this assignment is to motivate students to seek application of waveform coding techniques for digital audio transmission and digital audio recording. The assignment has two parts: Part A and Part B. PART A: Implementation of µ-law and A-law Compander (40 marks) Most modern communications systems operate in the digital domain for various reasons. However, most practical signals handled by these systems are naturally analogue in nature. Thus, an interface is needed between the signals and the systems handling them. This interface is called analogue-to-digital converter (ADC) and it’s reciprocal, digital-to analogue converter (DAC). The three main functions of the ADC are sampling, quantization and encoding.
