Is analog higher quality than digital?
Analog audio, although it can offer a warm and natural sound, is susceptible to noise and distortion during the recording, playback, and transmission processes. Digital audio has the advantage of being easily stored, copied, and transmitted without loss of quality.
Is analog more powerful than digital?
Analog signals are much higher density, and can present more refined information. Analog signals use less bandwidth than digital signals. Analog signals provide a more accurate representation of changes in physical phenomena, such as sound, light, temperature, position, or pressure.
Why is 4-20mA so common?
The reason why we use 4–20mA is that between these two *noise is very less, *transmission is easy, *easily generated. The reason we start from 4 MA is that, in case the power failure is there or some circuit breakdown happens, then the value should trip to 0(zero), and when the output is zero, then it will show 4 MA.
Why use 4-20mA instead of 0 20mA?
In this case, it would be extremely difficult to identify that either 0mA current is due to open circuit of the transmitter or it is due to no pressure of the fluid. Hence, if the transmitter is calibrated to generate current signal in the range of 4-20mA, the faults like open circuits can easily be detected.
