ABSTRACT:
An electronic musical instrument capable of producing a large number of harmonic contents with a small number of calculation circuits. A composite wave consisting of plural harmonics can be mathematically expressed as a multiplication of a factor including an order number of a harmonic and a factor or factors not including an order number of a harmonic. The instrument according to the invention utilizes this principle and produces a composite wave by first obtaining these two kinds of factors individually and thereafter multiplying them together.
An example of the invention capable of calculating four harmonics simultaneously and another example capable of calculating two harmonics simultaneously are described.
