摘要： A plurality of wave samples, each being generated successively, are respectively weighted by, for example, being multiplied by a plurality of wave functions generated corresponding to the plurality of wave samples. The plurality of weighted wave samples are summed to obtain a desired wave. The kind of each of the plurality of wave samples generated susseccive- ly is changed at each time when the value of corresponding one of the plurality of wave functions becomes zero. Therefore, the apparatus comprises wave generators for generating the wave samples successively, wave function generators for generating the wave functions successively, multipliers for multiplying the wave samples by the wave functions respectively, and adder for adding all of the outputs of the multipliers to generate the desired wave, and a wave changing circuit for changing the kind of each of the wave samples when the corresponding one of the wave functions becomes zero.
摘要翻译：分别依次生成的多个波形样本分别通过乘以与多个波形样本相应产生的多个波函数进行加权。将多个加权波样本相加以获得期望的波。每当多个波函数的相应一个值的值变为零时，每次产生的多个波形样本中的每个波形样本的种类被改变。因此，该装置包括用于连续产生波形样本的波形发生器，连续产生波函数的波函数发生器，用于乘以波函数的波形乘法的乘法器和用于相加乘法器的所有输出的加法器，期望波，以及波形变化电路，用于当相应的一个波函数变为零时，改变每个波样的种类。

摘要： A circuit effects regular multiplication of two field elements in a Galois field GF(2 m ). Each of the field elements is expressed by an m-bit binary member. The two field elements are applied to a binary multiplier array which generates (2m - 1 )-bit partial prod- cuts. The partial products are divided by a generator polynomial of the Galois field to produce final m-bit binary products.

摘要： An electronic musical instrument has a generator assigner (2) for supplying note data and octave data by key stroke, a top octave synthesizer (3) for generating 12 highest pitch signals for each note, a circuit (5) for selecting one highest pitch signal from the 12 highest pitch signals according to note data, a binary counter (6) for dividing said highest pitch signal to produce several pitch signals, and circuits (7) for selecting one pitch signal out of several pitch signals obtained by the binary counter. Further circuits (10) are controlled by both octave data and note data to generate octave series tone signals and non octave series tone signals such as quint series tone signals.
