I'm studying some notes on latches and flip flops. After the introduction of the D flip flop, the notes go on to explain its function - how it works. However, the first circuit diagram contains this weird circuit symbol :
Does anyone recognize it?
In case it helps, here's the full circuit diagram :
Could it be just a symbol replacing the whole D flip flop? In that case the inverters seem to be there so that we can get the 2 complementary Q outputs. I don't get the whole feedback thing though.
