Digital phones are more reliable than analog phones. The digital signals are easier to produce and the technology is more reliable than that of analog signal.
Digital GND has more noise than Analog GND. So never mix up Digital GND to Analog GND to avoid the coupling from Digital to Analog GND
The advantages of an analog watch over a digital watch are that analog watches can be more durable in some facets, than a digital one. Many watch enthusiasts also feel that analog watches are more aesthetically pleasing than digital watches.
The advantages of digital radio over analog radio are digital radios get more channels than analog, they are clearer in sound and signal and have more additional features.
Digital aerials get a better quality of picture than do analog aerials. in addition, digital aerials can get high definition signals over the air,where analog aerials cannot.
Digital stereo plotter is more accurate than the analog one in producing maps.
Digital is cheaper for two possible reasons. The answer will be determined by your question of type of digital as in physical components or radio based transmissions. Number one: Digital devices can be made smaller with less components than analog. Number two: More information can be transmitted over the same available transmission space using digital than can be with analog.
Bluetooth is a digital communication interface. It tends to be used for audio signals more than other applications so it is often perceived as carrying analog audio. Despite the appearance, it is definitely digital and not analog.
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
in a digital meter you get a digital value of your measurement. but in analog meter you have to check the position of the pin along the scale and find out the value.
Analog devices are everywhere. Clocks and watches were all analog until the coming of the digital age. Some early computers were analog, worked by manipulating voltages rather than binary digits. Broadly, devices are either analog or digital.
