| Abstract: | The technique of designing micro-electronic organ with eight musical scales is introduced.It gives the method of design parameters based on RC sine-wave oscillation line.The frequency of la is 440 Hz,which meets the international standard on C harmonica.A group of reference value and some methods are given.It proves that it is convient and inexpensive to design micro-electronic organ with this method. |
| Keywords: | electronic organ analog line frequency RC sine-wave oscillation line eight musical scale |
