Vhen comparing the generation of analogue output from a digital system using WM and DAC which of the following statements is NOT true? PWM generally has limited resolution compared with DAC PWM generally has better noise performance than a DAC PWM is a lower cost and simpler method of generating analogue output thar using a DAC. DACS tend to have a higher system cost than the equivalent system implemented using PWM
