  2. What is the Tustin approximation?
  3. Which order hold function is best suited for signal recovery?

What is first-order hold circuit?

The first-order-hold (FOH) method is a mathematical model to reconstruct the sampled signals that could be done by a conventional digital-to-analog converter (DAC) and an analog circuit which is called an integrator.

What is the Tustin approximation?

Absfract-The Tustin approximation is a simple way for determina- tion of a discrete-time representation of a continuous-time control system and is sufficiently precise, if a sampling interval is chosen properly.

Which order hold function is best suited for signal recovery?

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.
