To isolate a patient from getting connected to stray voltages. An isolation transformer is used and batteries power it to further isolate you from the real world. Also for sensitive measurements to eliminate some of the noise and current loops.
while conversion of analog signal to digital signal, we need to convert continuous analog signal to discrete signal. this can be done by dividing the analog signal into specific time slots. this process is known as sampling. there is a condition for sampling that can be given as follows. fs<=2fm
The sampling rate
In analog to digital conversion, 'accuracy' refers to how closely the digital representation of a signal matches the actual analog input, reflecting the fidelity of the conversion process. 'Resolution,' on the other hand, indicates the smallest change in the analog signal that can be detected and represented in the digital format, typically determined by the number of bits used in the conversion. Higher resolution allows for finer distinctions between different signal levels, while greater accuracy ensures that those levels are represented correctly. Together, they influence the quality and reliability of the digital output.
Analogue to digital is a conversion process not a transmission process.
You would utilize a VoIP adapter in the conversion of analog voice signals into digital IP packets. These adapters also have the ability to convert digital IP packets into analog voice streams.
Transforming analog signals to digital is known simply as analog to digital conversion, sometimes shortened to A-D conversion.
MODEMs do this function.
ATA (analog telephone adapter
DA conversion or D-to-A conversion.
Analog-to-digital conversion
the Sampling Rate.
AD is Analog to Digital conversion the use is to do digital measurements of analog voltages and currents, a computer soundcard is an AD converter that convert analog sound to digital sound so that it can be played on a computer, and DA is the opposite, digital to analog conversion, the digital sound on the computer is converted to analog sound to drive a speaker or headphone

The conversion of analog video to a digital format, or vice-versa.

Attractors of Hopfield network can be considered as digital presentation of analog inputs. Every analog input is classified as "hear" to some of attractors, so attractor (which is vector, including binary output of neurons) is digital conversion if analog input (vector, including input signals of neurons.
