Which statement about an On-Off Control is correct?

 The switching frequency increases with the switching hysteresis of the controller.

 The fluctuation of the controlled variable is independent of the switching hysteresis – it only depends on the setpoint value.

 The smaller the switching hysteresis of the control device, the smaller the fluctuation of the controlled variable and the higher the switching frequency.

 The bigger the switching hysteresis of the controller, the lower the fluctuation of the controlled variable and the smaller the switching frequency.

 The smaller the switching hysteresis of the control device, the higher the fluctuation of the controlled variable and the smaller the switching frequency.
