查询词典 alternation

Alternation of generations can be divided into two basic types, one for the same shape alternation of generations, the sporophyte and the gametophyte in the morphology similar size, only cytology and physiology are different, such as Ulva, etc.; another type of shape alternation of generations, that is, in the sporophyte and gametophyte morphology and size are also significant differences.

Compared to the ordinary PLL circuits, it can endure the short time appearance that occurs once in a horizontal line of the sync signal. It can adapt to the phase alternation character of a PAL video signal and recognize the phase alternation line. The local color sub-carrier can be generated for synchronous demodulation by the circuit.
