SIGNAL PROCESSING LAB REVIEW

The most important thing that this lab taught me was the difference between a DSP processor and a general processor. Most general purpose microprocessors are present in personal computers. They are often used for computation, text editing, multimedia display, and communication over a network. Other microprocessors are part of embedded systems. These provide digital control over practically any technology, such as appliances, automobiles, cell phones, industrial process control, etc.
The DSP processor, on the other hand, is a particular type of microprocessor. DSP stands for digital signal processing. It is basically any signal processing that is done on a digital signal or information signal. A DSP processor is a specialized microprocessor that has an architecture optimized for the operational needs of digital signal processing. DSPs also tend to be two to three times as fast as general-purpose microprocessors. This is because of architectural differences. DSPs tend to have a different arithmetic Unit architecture; specialized units, such as multipliers, etc. In this lab we have extensively used code composer studio for making the programs.Some of the programs we based on the concepts that we learnt from last semester in signals and systems. After completing this practical lab I have understood the importance of DSP and how it is used in applications such as audio signal processing, audio compression, digital image processing, video compression, speech processing, speech recognition, digital communications, digital synthesizers, radar, sonar, seismology and bio medicine.
