Description: This application report describes how to simultaneously create a sine wave, a ramp, and a dc level with pulse-width modulated (PWM) signals from Timer_A and Timer_B on the MSP430 ultralow power family of microcontrollers,and enlarge the voltage by the power triode transistor to meet the basic requests.with a 4*4 keyborad,we can choose the type ,range and frequency of the wave.
