What is difference between finite precision and infinite precision?? I think analog signals are referred to have infinite precision while discrete/digital signals are referred to have infinite precision

Please kindly explain with examples

The terms would seem mostly self-explanatory - analog signals are defined by a continuous function usually so the function can be defined at any value you wish - hence infinite precision. Digital signals, being digitised, are sampled at finite points and hence cannot give greater precision than the rate at which they are sampled. Signals have to be digitised in order to use on a computer though.
