| Abstract: | DDS technlogy is a kind of digital frequency synthesis technology that synthesizes the wave directly from the concept of phase,e design proposat of the sine and square waveform generator,based on the ultra tow-power microcontrofler MSP430F5438 and the DDS chip AD9850 is introduced.It can provide Sine and square wave,the range of which is from 1Hz- 10MHz.The frequency can be set by the keyboard,and it can generate a step frequency signal by different steps.The amplitude of the signal also can be adjusted.Through experiments testing,it can be seen that this kind of signal generator designed has high accuracy,wide frequency, simple structure,easy to use and high reliability.The output signal has stable frequency and has no obvious distortion. |
