The dimming frequency is dependent of the decoder's make,
and sometimes is considerably less than 50Hz.

Continuous dimming is a relic from the times when bulbs were used,
and due to the filament's inertia, can be done at a rather low rate.

Today dimming mainly only makes sense for high/low beam headlight control.

So when output-dimming is off, no LED will flicker whatsoever.

It may be seen, however, when you have more than one protocol active at the same time,
e.g. DCC and Märklin-Motorola, and the lights are connected single-ended to one pickup.

This is an effect generated by the CU's timing when sending the telegrams out.
