Adaptive Cancellation of Periodic 60 Hz Noise using ATmega32

An active noise canceler to eliminate the 60 Hz noise found in electrical signals due to AC power-line contamination. 60 Hz noise is frustrating for anyone trying to make sensitive measurements of low voltage processes (eg. Electrocardiogram measurements), record audio from electrical instruments (eg. guitar “hum”), or use electronic systems near an AC transformer. The
