Don't get your signals crossed

摘要

Despite the benefits of the digital revolution over the past two decades, analog is still alive and very well. We hear more than beeps and we see a spectrum of colors at an array of intensities. As long as humans are involved, analog signals will be of great, sometimes life-saving, importance. Therefore, it is critical to have a conversion device - one that can take in analog signals and transform them into digital ones as well as one that can take in digital signals and convert them into analog ones.
