摘要

P A.REVERBERATION DEVICE IN WHICH THE FREQUENCY BAND OF THE REVERTER SOUND IS EXPANDED. / P P B.CARACTERIZES IN THAT IT HAS A SIGNAL ENTRY TERMINAL PROVIDED FOR RECEIVING A SIGNAL OF INPUT, OPERATIONAL AMPLIFIER HAVING REVERSE INPUT TERMINAL, INVERSE INPUT TERMINAL AND OUTPUT TERMINAL, REVERSE INPUT TERMINAL CONNECTED TO SIGNAL INPUT TERMINAL THROUGH IMPEDANCE OF ENTRY, THE NON-REVERSE ENTRY TERMINAL CONNECTED TO A REFERENCE POINT, THE OUTPUT TERMINAL CONNECTED TO THE REFERENCE POINT THROUGH AN INDUCTANCE CONSTITUTING A LOAD FOR THE CIRCUIT AND A FIRST IMPEDANCE, WHILE A SECOND IMPEDANCE IS CONNECTED BETWEEN THE REVERSE INPUT TERMINAL OF THE OPERATIONAL AMPLIFIER AND THE CONNECTION POINT BETWEEN THE INDUCTANCE AND THE FIRST IMPEDANCE, THE INDUCTANCE BEING CONNECTED SO THAT IT PLAYS THE ROLE OF A MEANS OF CONTROL OF THE REVERBERATION DEVICE. / P P C.INVENTION APPROACH NOTES THE ANALYSIS OF SOUNDS. / P
