Filter Constant K3 |
(Trunking Wide, Filter Constants) |
Selects the K3 Filter Constant value, which is used when more than 16 seconds elapse between Received Signal Strength Indication (RSSI) samples (see also the RSSI Thresholds fields). The selected Filter Constant K3 value is used by the Filter Threshold Constant T3. This selection can apply for all Trunking Systems and therefore to all Trunking Personalities.

Modifications of Filter Constants should only be performed by a Motorola Field Technical Representative. |

The RSSI filter has the following characteristic Filter Val. = (Filter Val. * K + Current Reading * (10 - K)) / 10 where the domain of K is {K: K = K1, K2, K3} and 0 (no filter) <= K3 <= K2 <= K1 <= 9 (heavily damped filter). |
In a SmartZone system, the constants K1, K2, and K3 are designed to reduce filter damping as time between sampling increases. |
