本文较全面地叙述了数字式电子综合法的基本原理。用此方法为例子设计了电视同步信号中的复合同步信号、复合消隐信号、以及色同步消隐门(迂回门)信号,用电子计算机对所得逻辑函数进行化简(组合逻辑函数输出为单变量的化简)。最后,将所得结果用计算机进行模拟验证,计算机打印的波形与原设计的完全一致,证明了所得结果的正确,从而校正了著作中相应部份结果的错误。
This article more fully describes the basic principles of digital electronic synthesis method. Using this method as an example, the composite synchronization signal, composite blanking signal and color burst gate (detour gate) signal in the TV synchronization signal are designed, and the resulting logic function is simplified by the electronic computer (the output of the combined logic function is single Reduction of variables). Finally, the simulation results obtained by the computer simulation, the computer print the waveform exactly the same as the original design, the results proved to be correct, thus correcting the corresponding part of the results of the error.
