Apparatus of the reverberation in which the frequency of the sound reverbere is expanded

摘要

P a.appareil of reverberation in which the frequency of the sound reverbere is expanded. / p & & p & b.caracterise in that it comprises a terminal of the input signals provided for to receive an input signal, an amplifier operational having an input terminal reversed, an input terminal not reversed and an output terminal, the input terminal reversed since connected a terminal of the input signals by means of an input impedance, the input terminal not reversed since connected has a point of reference, the output terminal being connected at the point of reference by means of an inductor forming a load for the circuit and a first impedance, while a second impedance is connected between the input terminal reversed of the amplifier operational and the point of connection between the inductance and the first impedance, the inductance being connected so that it plays the role of a control means of the apparatus of the reverberation. / p & & p & c.l' invention applies in particular to the analysis of the sounds. / p
