Its in analog. You need to convert it to digital.

The question of converting the analog signal into a binary code is difficult to solve.

If x (t) - the analog signal to be converted into a binary code, it is also necessary to have known accuracy of the conversion (ie, the weight of the least significant bit of binary code) and discrete time (how much time is needed to perform another conversion signal).
