Abstract	Pseudo-random multi-frequency (PRMF) signal's bandwidth is controllable, its energy concentrated on several frequencies, which equally spaced on log-scale coordinate, and it is used as excitation for electrical exploration to improve the working efficiency. To realize high precision data acquisition and processing of pseudo-random signal in electrical exploration, PRMF multi-function receiver for electrical exploration is developed. This receiver adopts up-to-date electronics and technology, such as low-power Pentium-166 PC/104 embedded industrial computer, 24-bit CS5321/5322 A/D converter module, high reliable Actel anti-fuse FPGA, 32-bit data acquisition and processing software based WINDOWS operation system, adaptive correlation synchronization, weak signal detection based on cross-power, digital filter de-noising, and so on. Above measures make the receiver owns the advantages of fast signal processing, large dynamic range, lightweight, easy usage, good anti-interference ability, ability to receive PRMF signal and rectangular wave. It can carry out major electrical exploration methods, such as resistivity method, induced polarization method (time and frequency domain), complex resistivity method, controlled source audio magnetotelluric (CSAMT) method, and so on.
