What is the transfer function of first order hold?

First-order hold (FOH) is a mathematical model of the practical reconstruction of sampled signals that could be done by a conventional digital-to-analog converter (DAC) and an analog circuit called an integrator.

What is ZOH and FOH?

In large sampling period nonlinear systems, the Taylor series method was used to improve the performance of the controller. First-order hold (FOH) and zero-order hold (ZOH) are used respectively in the discretization of input time-delay systems. The sampled-data representation of FOH and ZOH are both described.

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.

What is zero-order hold transfer function?

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.
