A Novel Signal Pre-processing Circuit for Prospecting Apparatus
By investigating the deficiency of traditional Rayleigh wave prospecting apparatus in effective dynamic range and exploration precision, a new signal channels based on circular amplifying floating-point ADC was brought forward. The signal amplifying and offset error self-compensation algorithm were discussed. Application analysis shows that, system Transient Dynamic Range/Tiptop Signal Frequency of the 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-ADC seismic prospecting apparatus.
