5.Through the equivalent transformation between the linear combination relation of the father-son state in the state equations and the incidence relation of the father-son state nodes in the weighted network, it is realizable to build the block contact of the general structure and the system state variable is the earliest starting time, and collect the incident matrices of the dividing branch nets in whole net, then the parameter matrices of the state space model are obtained.
10.This paper presents the design of signal preprocessing subsystem in a 3-D s. pectrum analysis system. The circuit units of active state-variable type BPF filter, automatic gain control (AGC),ADC,and microcomputer interface are designed and implemented.
