Zero-order hold used in practical reconstruction of continuous-time signals is mathematically represented as a weighted-sum of rectangular pulses shifted by:
A. Any multiples of the sampling interval
B. Integer multiples of the sampling interval
C. One sampling interval
D. 1 second intervals
Answer:B
Zero-order hold used in practical reconstruction of continuous-time signals is mathematically represented as a weighted-sum of rectangular pulses shifted by:
A. Any multiples of the sampling interval B. Integer multiples of the sampling interval C. One sampling interval D. 1 second intervals
Explanation: Zero-order hold is used to reconstruct the continuous-time signal which is represented as a weighted sum of rectangular pulses shifted by integer multiples of the sampling interval.
