The experiment conducted in this study aims to analyze and compare the performance of uniform PCM quantization and u-law non-uniform quantization. This is an important topic in digital signal processing as it provides insights on the efficacy of different methods of quantization in terms of preserving signal quality. The experiment involved the use of a sample data set and analysis of the resulting distortion and signal-to-noise ratio (SNR) for each method. The results obtained provide valuable insights into the effects of the different quantization methods and can be used to inform future decisions in digital signal processing applications.
