Coefficient Space and Presets

 Shown for the largest coefficient step size of 1/24 (smallest 1/63)

 Depending on coefficient resolution some quantization error exists, preset

tolerance is relaxed to ±1dB or ±1.5 dB

 Advisable for Rx equalizer to adapt to Tx and channel

 11

preset is advertised by Tx and may vary, but must fit between min reduced

and max full swing limits
