一种方波移相器及移相方法
摘要：
本发明公开了一种方波移相器，包括微处理器、移相模块以及触摸屏；所述微处理器分别和移相模块与触摸屏相连；移相模块包括分频器、100选1选择器以及100个D触发器，每个D触发器的信号输出端与其后的D触发器的信号输入端连接，第一个D触发器信号输入端直接接入待移相的方波信号；待移相的方波信号和每个D触发器的输出信号都连接到100选1选择器，分频器的输出端与每个D触发器的时钟信号输入端相连，本发明通过触摸屏进行指令输入和移相信息显示，并通过处理器对指令信息进行采集与处理，并将处理完的指令信息发送给采用CPLD的移相模块，CPLD根据接受到的移相指令对输入的方波进行移相，本发明结构简单，频率带宽大且，且制造简单，生产成本较低。
摘要（英）：

The invention discloses a square wave phase shifter which comprises a microprocessor, a phase shifting module and a touch screen. The microprocessor is connected with the phase shifting module and the touch screen. The phase shifting module comprises a frequency divider, a 1 in 100 selector and 100 D flip-flops. The signal output end of each D flip-flop is connected with the signal input end of the subsequent D flip-flop. The signal input end of the first D flip-flop is directly connected with a square wave signal to be shifted. The square wave signal to be shifted and the output signal of each D flip-flop are connected with the1 in 100 selector. The output end of the frequency divider is connected with the clock signal input end of each D flip-flop. According to the invention, instruction inputting and phase shifting information displaying are carried out by the touch screen; the processor collects and processes instruction information; the processed instruction information is sent to the phase shifting module which uses CPLD; the CPLD carries out phase shifting on an input square wave according to a received phase shifting instruction; and the square wave phase shifter has the advantages of simple structure, large frequency bandwidth, simple manufacturing and low production cost.
