| Abstract: | A signal generator carrying the ultra low frequency with the function of arbitrary value was designed, centering on the application of single-chip. The multiple techniques of digit wave form was adopted. Via the hardware circuit and software program, the signal generator could output the waveform which was user-defined, such as sine, triangle, square, saw-tooth shape, etc. The function of the lower frequency was extremely superior. The principle of the wave generation, hardware circuit and software design was presented. The frequency and amplitude value of the waveform can be changed discretionarily. Compared with other normal signal generator, its advantage is the user-defined output wave and the high accuracy of low frequency. |
