<p>PHN. 9421 6 An artificial reverberation device according to the invention comprises at least two basic units connected in series, each unit comprising a series connection of a first delay line, an adder circuit and a second delay line, a feedback circuit from the output of the second delay line to the adder and a transmission circuit from the input of the first delay line to the adder, the delay times of both delay lines being equal. According to the invention at least part of the first delay line of one unit functions as at least part of the second delay line of the unit preceding the said one unit, or, at least part of the second delay line of the one unit functions as at least part of the first delay line of the unit following the said unit, or both. In this way, multiple echo times are obtained with a minimum of delay lines.</p> |
