发明名称 Electronic musical instruments of harmonic wave synthesizing type
摘要 There are provided a plurality of key switches which respectively designate the pitches of the musical tones to be generated, a frequency number generator which generates frequency numbers corresponding to the respective key switches, a harmonic order number generator which generates harmonic order numbers representing the orders of the respective harmonic components, an arithmetic processor for producing a multiplication product of the frequency number and the harmonic order number, an accumulator which repeatedly accumulates the output of the arithmetic processor of each harmonic order at a predetermined speed, and a sinusoid table including a memory device storing the amplitude values at respective sampling points of a sinusoidal wave for generating the amplitude values of the sinusoidal wave corresponding to respective harmonic components thereby producing the harmonic components.
