91. DAC Basics

Question.5

Katie is generating a sine wave using the DAC of her microcontroller, but the output looks rough and stepped due to the discrete DAC levels. What is the best and most efficient approach to smooth out the waveform and produce a continuous analog signal?

Connect an RC low-pass filter.
Connect an RC High-pass filter.
Reduce the DAC resolution to decrease step granularity.
Increase the microcontroller’s clock speed to generate smoother steps.
