【Abstract】 In high accuracy experiments,the data transmitted by single chip microcomputer,through D/A conversion and calculating amplifier,turn out triangular wave and sinusoid,etc.The wave form is explicit,with good frequency adjustment and stability performance.Only by varying its software,not hardware,its possible to obtain more complicated wave form.更多还原
