Everything in your natural world is analog; however, what does the term mean? An analog signal is a single electrical that defines an intended number. It might be represented as voltage or current. On the other hand, digital signals possess more than one electrical signals that only take two values – more substantial than a specified level or lower than that. If you are new to the electronics, sound and imaging world, then you are confused about the different formats that have emerged in the market. Everything is all about input and output. How can you convert an analog signal to a digital one or the other way around?
An analog signal is a point-to-point interface between an output and input. This connection is electrically balanced and offers a profound immunity to EMI (Electromagnetic Interference). You can split various analog outputs to get different inputs; however, you cannot “Y” different outputs together. The analog signal is in the form of time-varying analog voltage, which can range over 100Db. All the analog signals are categorized based on the voltage magnitude, and it follows only one direction at any moment, from the input to the output. Compare analog input vs digital input here!
You can have a long cable, but the capacitance limits them. There are some cases that you can have a long cable that is around 300 meters. Analog interfaces are mature and straightforward and are easy to troubleshoot. They are quite reliable and don’t need impedance-matching between output and input. In most cases, you don’t have to consider latency issues.
LabJack Digital interfaces, on the other hand, are entirely different. The professional audio industry has standardized various point-to-point audio formats. They are meant to protect the final user from the complexity of the interface as well as the data itself. AESx is the most commonly used, and just like the analog signal, it is a one-way connection that goes from the output to input. The significant difference between this interface and analog is that it can carry two channels through a single twisted-pair. There are numerous to the digital interface. You are going to have two channels in a single cable and high immunity to electromagnetic interference.
Well, if you are trying to figure out the perfect one to utilize, then it all depends on many unique factors. Each has its advantages and shortfalls; however, in today’s modern world, the digital interface has been the most preferred connection type.
