运用拓扑方法求解校正网络的传递函数,它可直接到写出传递函数分子和分母各项,而不是像过去常用克希荷夫定律求解行列式各项。后者的缺点是要对0项的运算和对对消项的运算。特别是对于复杂的校正网络,主要的计算工作量是对0项和对消项的计算,不仅浪费机时,也降低了计算精度。应用拓扑方法求解校正网络的传递函数就能避免上述缺点。因而它得到越来越广泛的应用。
Using topological methods to solve the transfer function of the correction network, it can directly write out the numerator and denominator of the transfer function, rather than solving the determinant as usual using the Kirchhoff’s law. The latter disadvantage is the operation of 0 and the elimination of the operation. Especially for complex calibration networks, the main computational workload is the calculation of 0 items and elimination items, which not only wipes the machine time but also reduces the calculation precision. Applying the topology method to solve the transfer function of the correction network can avoid the above shortcomings. Thus it gets more and more widely used.
