Which of the following is not a disadvantage of oversampling?(a) High cost(b) More storage space(c) Less accuracy(d) High power consumptionI had been asked this question at a job interview.I'm obligated to ask this question of Data Conversion topic in section Digital Communication Techniques of Avionics |

Answer» CORRECT choice is (c) Less accuracy For explanation: Accuracy of the conversion increases with an increase in sampling rate since discretization is REDUCED and we get a better digital replica of the original signal. As the frequency is HIGH and the time period between samples are very low huge amounts of data are recorded and hence require high power and storage space EVENTUALLY leading to high costs. |
