A comparative study of FPGA based CIC filter with delta sigma modulator and adaptive filter for audio noise elimination

Abstract

Cancellation of noise from an audio signal in digital domain is a biding and trendy task. The paper focuses on the comparative study of FPGA based multirate Cascaded Comb Filter along with a delta sigma modulator and Adaptive Filter using Normalized Least Mean Square (NLMS) algorithm. The comparison is done in the domain of noise shaping, device utilization… (More)
