Abstract:
Digital filter design plays an important role in the digital signal processor (DSP) field. Filtering is one of the most useful signal processing operations. Digital signal processors, such as the TMS320 family of processors, are used in a wide range of applications, such as in communications, controls, speech processing. The two methods of designing a digital filter are infinite-impulse response (IIR), and finite-impulse response (FIR).The IIR filter can be designed and implemented using floating point digital signal processor. Digital signal processors are now available to implement digital filters in real time.
This project show how to implement a digital IIR filter using the Cascaded (second order section), direct form II structure and the generation of a sine wave using a difference equation on DSP chip.
