The process of converting a continuous analog signal to a discrete dig

1.	The process of converting a continuous analog signal to a discrete digital signal is called?(a) Discretisation(b) Sampling(c) Preemphasis(d) ReductionI had been asked this question in an interview for internship.My query is from Data Conversion in chapter Digital Communication Techniques of Avionics
Answer» Right CHOICE is (b) Sampling The BEST I can explain: An analog signal is continuous and hence contains an INFINITE number of points. The process in which this continuous signal is discretized is called as sampling. The sampling period DETERMINES the ACCURACY of conversion.
