| Abstract: | The frequent source used as frequency scale, the time signal generator of FIRIG-B code gets different frequency signals from countdown chain and provides the system with local standard frequency and standard time signal. The generator is composed of input shaping circuit, frequency divider circuit, numeric switch phrase shifter circuit, delay second formation circuit, local second formation circuit and so on. The design includes plan establishment, bottom layer analysis, top layer integration, simulation and etc. There are also 2 parts in bottom layer analysis: frequency dividing element and delay pulse generating element. |
