Analog signal generation fundamentals

“

- So far in this course, we've focused on Analog Input, or acquisition tasks, which use an Analog-to-Digital Converter to turn a signal from the physical world into a series of digital values. Now it's time to turn the focus around and go the opposite direction to perform Analog Output, or a generation task. Analog Output uses a different device called a Digital-to-Analog Converter, or DAC, which takes a series of digital values as it's input, and then generates the corresponding output signal in the physical world. Since the digital input can only represent discreet values with finite precision, the output signal it generates will be at discreet levels, which look like a series of steps when plotted over time. It's common to use some sort of analog filter on the output signal coming from that DAC to smooth out the sharp edges so it looks more like a natural occurring continuous analog signal. There is several key…
