Multiband fir Filter Design and implementation to recover real- time corrupted input speech using DSK TMS320C6711

Abstract

In this paper, the five-band notch filter was designed using MATLAB and implemented by the floating-point digital signal processor TMS320C6711 based on TI's DSP starter kit (DSK) board connected to the parallel port of the PC through the DB25 cable included with the DSK package. The original segment of symphony orchestra corrupted two undesired sinusoids at frequencies of 750Hz and 1750Hz is conduced to input of DSK to produce the corrupted input signal which is saved in the wave file (Corrupthandel.wav) for the digital signal processor. The two noise sinusoidal signals are generated by the real-time signal generator. The output signal of DSK is plotted on an digital oscilloscope, on CCS window or on an earphones
