Hysteresis band filter#
-
float uz_signals_hysteresisband_filter(float input, float upper_limit, float lower_limit)#
Passes the input signal through if it is inside the hysteresis band limited by the upper or lower limit, otherwise the output is zero.
- Parameters:
input – Any input signal
upper_limit – Upper limit of the hysteresis band
lower_limit – Lower limit of the hysteresis band (needs to be smaller than the upper limit)
- Returns:
float filtered signal
Example#
1#include "uz_signals.h"
2int main(void) {
3 float input = 2.0f;
4 float upper_limit = 0.5f;
5 float lower_limit = 0.2f;
6 float output = uz_signals_hysteresisband_filter(input, upper_limit, lower_limit);
7}
Description#
Passes the input through if it is inside a hysteresis band limited by the upper and lower limit values. Otherwise the output is 0.
