Test: Signal Reconstruction - Question 1

Sampling can be done by:

Detailed Solution for Test: Signal Reconstruction - Question 1

Explanation: Sampling is the process in which the continuous systems are sampled by the application of the zero order hold and can be done by all the three methods.

Test: Signal Reconstruction - Question 2

The first step required to convert analog signal to digital is :

Detailed Solution for Test: Signal Reconstruction - Question 2

Explanation: Sampling is the process in which the continuous systems are sampled by the application of the zero order hold and is the first step in the conversion of analog to digital signals.

Test: Signal Reconstruction - Question 3

Sampling is necessary :

Detailed Solution for Test: Signal Reconstruction - Question 3

Explanation: Sampling is the process where the continuous systems are converted into discrete time systems with the help of zero order hold of the signal and sampling is necessary where high accuracy is needed.

Test: Signal Reconstruction - Question 4

Sampled data technique is appropriate as:

Detailed Solution for Test: Signal Reconstruction - Question 4

Explanation: Sampled data technique refers to the data which is sampled and is appropriate as for long distance communication, for accurate transmission and multi channel transmission.

Test: Signal Reconstruction - Question 5

Signal sampling reduces the power demand made on the signal.

Detailed Solution for Test: Signal Reconstruction - Question 5

Explanation: Signal sampling refers to the sampling of the signal and reduces the power demand that is the power required by the signal and is therefore helpful for signals of weak origin.

Test: Signal Reconstruction - Question 6

The use of sampled data control system are:

Detailed Solution for Test: Signal Reconstruction - Question 6

Explanation: Sampled data control system is the system where the data used is sampled and is used whenever a transmission channel forms a part of closed loop system.

Test: Signal Reconstruction - Question 7

_______________ is a sampling pattern which is repeated periodically

Detailed Solution for Test: Signal Reconstruction - Question 7

Explanation: Multi-order sampling is a sampling pattern in which the sampling is of different signals and which is repeated periodically.

Test: Signal Reconstruction - Question 8

For the successful reconstruction of signals :

Detailed Solution for Test: Signal Reconstruction - Question 8

Explanation: Reconstruction of signals refers to the conversion of the discrete time signals into continuous tiem signals and for the succesful reconstruction of signals sampling frequency must be greater than or equal to the message signal but ideally it is always preferred to be greater.

Test: Signal Reconstruction - Question 9

The signal is reconstructed back with the help of

Detailed Solution for Test: Signal Reconstruction - Question 9

Explanation: The signal is reconstructed that is the process of converting the discrete time signals into the continuous time signals and this can be done with the help of hold circuits or extrapolations.

Test: Signal Reconstruction - Question 10

Aliasing is caused when:

Detailed Solution for Test: Signal Reconstruction - Question 10

Explanation: Aliasing refers to the process when the discrete time signal is recontructed back then due to the error some part of the signal is lost and is caused when sampling frequency must be less than frequency of message signal.
