1. In order to obtain digital data after the sampling of a time-continuous signal, the

samples should be

A. quantied (Quantication) B. Tailed (Tailing)

C. amplied (amplication)

choose the correct response.

2. If the sampling time is small the

A. Information may be lost

B. The required resources for data transmission will be large.

choose the correct response.

3. If the sampling time is huge, then

A. Information will be lost

B. The required resources for data transmission will be large.

choose the correct response.
