Abstract :
This system design a function signal generator, with MSP430 as control core, based on DDS chip AD9850, first of all produced 100 Hz ~200 KHZ to 1 MHZ (extensible) adjustable frequency of the sine wave signal, and then through waveform transform circuit, produce square wave and triangular wave signal, Through the use of voltage amplification, can be in 1 k Ω load resistance on the 100 hz ~200 KHZ sinusoidal signal in the range of the output voltage amplitude values of peak to peak VP - P is adjustable within 0 ~5 v. Control system adopts LCD display and voice prompt, convenient.
