“…The detection of significant activity within the passband of an analog filter is usually accomplished through integration and level detection (Boudrot, 1972;Pasquali, 1969). Absolute value or precision full-wave rectifier circuits take the signal from the filter, invert the negative half of the waves, and pass the signal on to an integrator that smooths the ripple from the signal.…”

I ran across the statement very recently in the book of Theophrastus On Inspiration that many men have believed and put their belief on record, that when gouty pains in the hips are most severe they are relieved if a fluteplayer plays soothing measures, That snake-bites are cured by the music of the flute, when played skillfully and melodiously, is also stated in a book of Democritus, entitled On Deadly Infections, in which he shows that the music of the flute is medicine for many ills that flesh is heir to. So very close is the connection between the bodies and the minds of men, and therefore, between physical and mental ailments and their remedies.Aulus Gellius (c. 160 A.D.

“…Biofeedback apparatus ranges in complexity from the R-C circuit to the digital computer. Apparatus of intermediary complexity, cost, and function typically have been constructed using analog processing techniques (Boudrot, 1972;Helmer, 1975;Pasquali, 1969;Rouse, 1975). The present paper describes an inexpensive device (approximately $25) that precisely determines whether the period of a digital signal is within a criterion band of frequencies.…”

“…Purely analog systems have been used by Boudrot (1972) and Pasquali (1969). Digital filtering in the time domain has been demonstrated by Beatty (1971), Paskewitz (1971), and Sharp, Smith, and Surwillo (1975) using digital computers.…”
