Signal Conditioning Circuit Design Method Based on Case-Based Reasoning

Abstract

In order to improve the R&D speed of instrument and to reduce the R&D cycle, this paper presents a signal conditioning circuit design method based on case-based reasoning (CBR). The case base stores a number of case circuits, and each circuit’s feature information is described by a set containing at least one information entity; the description methods include: according to the user’s description information on the to-be-generated circuit, generate the first information entity set of to-be-generated circuit; take the first information entity set as the search keywords, search from the case base the case circuit of all or partial information entities of the circuit to be generated; according to the degree of correlation between the preset information entity and the case circuit, obtain the degree of correlation between the first information entity set and the searched case circuit; from the said case circuits searched, select the case circuit whose correlation degree is larger than the correlation threshold value as the target circuit; output the target circuit; through accepting the users’ modification of target circuit, obtain the circuit to be generated. Experimental results show: signal conditioning circuit image generation method, which is based on case reasoning, can effectively improve the efficiency of research and development.
