Abstract
An improved method for introducing self-tuning features in an active filter for detection of weak signals in a noisy background is described. The filter, which works at low frequencies (100Hz-10kHz), is provided with facilities for search and tracking. During an experiment, the filter was able to detect a sinusoidal signal of 1mV r.m.s. in a 10kHz-bandwidth background noise of 3mV r.m.s.
