| Abstract: | A wave generator was designed, the 10kHz, 30kHz, 50kHz Sine wave were filtered out by filter the square wave, the value of Sine of 10kHz, 30kHz and 50kHz is 6 v,2 v and 1 v. The square wave and triangle wave were obtained by shifting the phase of the three waves and adding. The frequency and voltage of three kinds of wave was A / D converted, the conversion results were displayed on 1 602. By using the microcontroller control LM3S811 as the control unit, through the buttons the output frequency and output voltage, phase, showing circuit were controlled. System of man-machine interface is friendly, stable, and meets the requirements. |
