Linear and Logarithmic Quantization (m10051)
Author: Lee Potter
Maintainers: Ricardo Radaelli-Sanchez, Mark Butala, Robert Morrison
Keywords: linear quantization, logrithmic quantization, quantization noise, Signal to Noise Ratio, SNR
Summary: In this module, we will use the 56002 to measure noise introduced by quantization and compare the performance of linear and logarithmic quantization. First, we will write a program to perform N-bit (N less than or equal to 16) linear quantization and logarithmic (mu-law) quantization. Then will use ... audio signals.

Multirate Filtering: Implementation on TI TMS320C54x (m10621)
Maintainers: Mark Butala, Matthew Berry, Douglas L. Jones, Ricardo Radaelli-Sanchez, Swaroop Appadwedula, Daniel Sachs, Robert Morrison
Keywords: banz, decimation, down-sample, DSP, interpolation, multirate sampling, multirate system, sample-rate compressor, sample-rate expander, serial port, up-sample
Summary: You will implement a multirate system that includes three fininte impulse response filters. The sample-rate compression and expansion factors can be controlled in real time using a MATLAB graphical user interface.
