Wide-Range Dynamic Signal Pre-Processing Circuit to Rayleigh Wave Seismic Prospecting Apparatus

摘要：

A novel method for Rayleigh wave signal pre- processing with a new structure ADC was proposed.By investigating the deficiency of traditional Rayleigh wave prospecting apparatus in effective dynamic range and exploration precision,this note brought forward a new floating-point ADC signal channel.Signal amplifying and offset error self- compensation algorithm were discussed.APP show that system Transient Dynamic Range/Tiptop Signal Frequency of fleet-level, middle-level &deep-level are 90db/1536Hz,90db/200Hz & 84db/156Hz respectively,and the upright exploration resolution of middle &deep-level is better than the traditional floating-point ADC and Σ-△ ADC prospecting apparatus.
