What is zoh derive the transfer function of ZOH?
The zero-order hold (ZOH) is a mathematical model of the practical signal reconstruction done by a conventional digital-to-analog converter (DAC). That is, it describes the effect of converting a discrete-time signal to a continuous-time signal by holding each sample value for one sample interval.
How do you find the zero-order hold?
The zero-order hold is a method which is widely used to reconstruct the signals in real time. In the zero-order hold reconstruction method, the continuous signal is reconstructed from its samples by holding the given sample for an interval until the next sample is received.
What is zero-order interpolation?
In addition to bandlimited interpolation, a variety of other interpolation procedures are commonly used. One, referred to as a zero-order hold, interpo- lates between sample points by holding each sample value until the next sam- pling instant. This generates a staircase-like approximation to the original sig- nal.
How does zero-order hold work?
The Zero-Order Hold block holds its input for the sample period you specify. If the input is a vector, the block holds all elements of the vector for the same sample period. You specify the time between samples with the Sample time parameter. A setting of -1 means the block inherits the Sample time.
