![]() ![]() This magnet induces a small current (that varies in voltage as the notes change) that is sent to an ADC. As the microphone senses the air pressure change, it moves around a small magnet based on the changes. the song) into some sort of recording sensor in this case, it could be as simple as a microphone. Assuming a guitarist wanted to record himself for later listening, they would simply play their own analog signals (i.e. The process that a signal goes through from starting as an audio signal and ending as a digital signal is rather straightforward. If you were planning to drop $10,000 on a new amplifier, wouldn’t you care about how signals are converted from the CD to your speakers? Of course, you would! ![]() ![]() Other than my own personal fascination with audio circuitry, the audiophile industry is the area where folks really, really, really care about signal performance. Many analog-to-digital conversions (ADC’s) and digital-to-analog conversions (DAC’s) that I hear about these days in the audiophile industry. This is a subject that we should all strive to understand from a qualitative point of view because this technology can improve our perception of the world around us. ![]() With all this ‘analog-to-digital’ and ‘digital-to-analog’ conversion happening all around us at nearly every waking moment of our existence (these days), it’s a wonder how it’s still such a mysterious topic. Listening to a song on the radio is a representation of what the original analog signal once was but now captured and reproduced over and over for years and years of continued enjoyment. Simply just reading this article can be perceived to be a ‘digital’ conversion of my ‘analog’ thoughts. Analog and digital signal performance is necessary to keep in mind.ĭigital-to-analog conversions (and back again) are a hot commodity in our present culture. Yet, we grow up and seem to spend most of our time attempting to turn these signals into a reproducible ‘digital’ copy so we can perceive them through a digital device. The sound of a stream running through a mountain meadow, the brown color of dirt, that screaming baby next to you all of these ‘signals’ are of an analog nature. We are born into a world of purely analog signals. ![]()
