Adaptive Noise Cancellation
FPGA implementation of ANC algorithms and performance analysis.An adaptive filter is essentially a digital filter with self-adjusting characteristics. It automatically adapts to changes in its input signals. Adaptive filters are the central topic in the sub-area of digital signal processing (DSP) known as adaptive signal processing.
Some example applications include the following:
Cancellation of noise in brain scans
Cancellation of mothers heartbeat to obtain clean signal of fetus heartbeat
Echo cancellation in communication systems
