What is the transfer function of a zero-order hold zoh )?

The transfer function of a zero-order hold system having a sampling interval T is 1s(1−e−Ts)

What is the Z transform of 0?

The z-transform of the zero order hold is 1.

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 hold and first order hold?

Zero Order means the function is constant, we interpolate the same value in the missing parts. First order means we can use linear function to interpolate (Line with a slope). Hold means we hold the parameters to be the same until the next sample.
