Dead zone function

float uz_signals_dead_zone(float input, float upper_threshold, float lower_threshold)

Outputs zero, if signal is within the deadzone. Outputs input signal substracted by either the upper or lower threshold otherwise.

Parameters:

• input – Input signal

• upper_threshold – Max limit for deadzone

• lower_threshold – min limit for deadzone

Returns:

float Returns signal

Example

Listing 95 Example function call provides region of zero output

#include "uz_signals.h"
int main(void) {
   float input=1.1f;
   float upper_threshold=10.5f;
   float lower_threshold=-20.5f;
   float output = uz_signals_dead_zone(input, upper_limit, lower_limit));
}

Description

The dead zone function outputs zero within a specified region. Otherwise it outputs the input subtracted from the threshold.

Table 9 Deadzone

input	output
input >= lower_threshold && input <= upper_threshold	zero
input > upper_threshold	input - upper_threshold
input < lower_threshold	input - lower_threshold
