Abstract

High-pass active filter, perfected, which being of special application in recordings and audio broadcasts, and relating the high frequencies or their harmonics of musical instruments, is essentially characterized by being constituted by an electronic circuit comprising an input buffer, followed by an active filter, properly speaking, that connects with an output buffer, there being a saturation indicator block of the input circuit and a similar block for the output circuit, with the particularity that the input buffer is constituted by an encapsulated circuit containing an rc network, followed by a differential amplifier, while the active filter comprises two differential amplifiers conveniently associated with an encapsulated circuit, containing a selective rc network and two transformer-adapters, it being provided that the salt blocks saturation indicators are constituted by two differential amplifiers it is associated with a luminescent diode, provided as an optical indicator means.
