For the successful reconstruction of signals :
A. Sampling frequency must be equal to the message signal
B. Sampling frequency must be greater to the message signal
C. Sampling frequency must be less to the message signal
D. Sampling frequency must be greater than or equal to the message signal
Answer:D
For the successful reconstruction of signals :
A. Sampling frequency must be equal to the message signal B. Sampling frequency must be greater to the message signal C. Sampling frequency must be less to the message signal D. Sampling frequency must be greater than or equal to the message signal
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.
