发明名称	ACCELEROMETER TRANSDUCER USED FOR SEISMIC RECORDING
摘要	<p>A system for acquiring environnemental information measurements. The 5 system (100) utilizes a sensor, (205) a front-end circuit, (310) a loop filter (315), a switch controller (206), and a recuced-oder loop control circuit to provide reliable data measurements while providing robust system behavior. The system further includes a sensor simulator (330) for simulating the operation of the sensor (205) and testing the operation of the front-end circuit (310) nd the loop filter (315).</p>
