Abstract :
About the Y/C and noise of digital television, this paper based on the DSP adaptive filter is applied for system identification and noise cancellation in the Y/C processing system. It expounds the principle of adaptive FIR filter based on LMS algorithm and application in system identification and the realization method on fixed-point DSP.
