Lock-in amplifiers were invented in the 1930's and commercialized in the mid 20th century as electrical instruments capable of extracting signal amplitudes and phases in extremely noisy environments... They employ a homodyne detection scheme and low-pass filtering to measure a signal' s amplitude and phase relative to a periodic reference.  2, record 1, English, - lock%2Din%20amplifier

Noise Suppression Filter. The patent describes a simple and inexpensive device for filtering undesirable high frequency noise from analog data outputs of a data processing system, which operates in two different modes and switches automatically from one to the other depending on the rate of change of data functions and on data transient amplitude with respect to full scale.  1, record 2, English, - noise%20suppression%20filter

Conventional multi-burner scanners have relied on the strength or amplitude of the flame signal to discriminate between burner flame-on and burner flame-off. This is most often done by using the amplitude output of the flame signal after bandpass or highpass filtering.  4, record 3, English, - flame%20signal%20amplifier
