The Hysteresis block is a simple buffer stage that provides hysteresis of the output with respect to the input.
The in_low and in_high parameter values specify the center voltage or current inputs about which the hysteresis effect operates.
The output values are limited to out_lower_limit and out_upper_limit.
The value of hyst is added to the in_low and in_high points in order to specify the points at which the slope of the hysteresis function would normally change abruptly as the input transitions from a low to a high value. Likewise, the value of hyst is subtracted from the in_high and in_low values in order to specify the points at which the slope of the hysteresis function would normally change abruptly as the input transitions from a high to a low value. In fact, the slope of the hysteresis function is never allowed to change abruptly but is smoothly varied whenever the input_domain smoothing parameter is set greater than zero.
