Filter Constant K1 |
(Trunking Wide, Filter Constants) |
Selects the K1 Filter Constant value, which is used when less than 8 seconds elapses between the Received Signal Strength Indication (RSSI) samples (see also the RSSI Thresholds fields). The selected Filter Constant K1 value is used by the Filter Threshold Constant T1. 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. |
