What is upsampling method?
Upsampling or Oversampling refers to the technique to create artificial or duplicate data points or of the minority class sample to balance the class label. There are various oversampling techniques that can be used to create artificial data points.
Why do we use Zoh in digital control system?
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.
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)
