How does an analog signal work?
An analogue signal uses some attribute of the medium to convey the signal's information. For example, an aneroid barometer uses the angular position of a needle as the signal to convey the information of changes in atmospheric pressure. Electrical signals may represent information by changing their voltage, current, frequency, or total charge. Information is converted from some other physical form (such as sound, light, temperature, pressure, position) to an electrical signal by a transducer which converts one type of energy into another (e.g. a microphone ).
Why do analog signals fail gracefully?
The greater the noise level, the more the analogue signal is disturbed, slowly becoming less usable. Because of this, analogue signals are said to "fail gracefully". Analogue signals can still contain intelligible information with very high levels of noise.
Why are analog circuits so hard to design?
Analogue circuits are typically harder to design, requiring more skill than comparable digital systems to conceptualize. This is one of the main reasons that digital systems have become more common than analogue devices. An analogue circuit is usually designed by hand, and the process is much less automated than for digital systems. Since the early 2000s, there were some platforms that were developed which enabled Analog design to be defined using software - which allows faster prototyping. However, if a digital electronic device is to interact with the real world, it will always need an analogue interface. For example, every digital radio receiver has an analogue preamplifier as the first stage in the receive chain.
