Humax Signal Strength/Quality
The Humax provides easy indications of strength and quality for each channel..
Freeview HD sets also allow such measurements. I have Googled ..but obviously inaptly ..to find how the Quality assessment is determined.. I imagine that the Transmitted sends out a 100% quality signal. It is interesting that the Quality is often the determinate factor not the Signal Strength. Hence i was seeking information as to the factors affecting the quality as well as it's measurement.. In passing.. I have tweaked many 470k and 10.7M coils in my time ..hence i am surprised in this digital age at the fragility of the Audio signal ..as in my tests to date.. it always fails before the everso complex digital signal. Am i alone in my unawareness? ![]() ![]() Stan |

It's a measure of how hard the tuners error correction is having to work to recover the original data using the built in redundancy in a digital signal. The more error correction the worse the quality. As the quality falls there's a narrow band where the picture starts to pixellate as the error correction fails to recover every bit in the original data. A small reduction then results in total failure and the picture is lost (The digital Cliff). Signal strength is a poor guide since it's simple to amplify the carrier signal, too much amplification comprimises the tuners abilty to resolve 0's and 1's

'very Interesting' as that Hun in Downtown Burbank used to say..
![]() The Panny supposedly measures Error Rate and during the reductions in signal strength i then did.. indicated 0+0E000 thru' out. I go to bed more aware than when i awoke.. Mnay thanks Stan |
