摘要： Provided is a highly sensitive sensor system that can improve the S/N ratio by use of an electronic circuit without complicating the sensor body or degrading temporal resolution. A broad spectrum sensor element outputs an electric signal corresponding to a detected physical quantity, the sensor driven by multiplying a carrier signal by m-sequence code. The spread spectrum signal, after phase adjustment, is used to demodulate the sensor output signal, which corresponds to the broad spread spectrum of the physical quantity. The electrical noise generated in the sensor is a broad spread spectrum and is suppressed by low-pass filtering so as to improve the S/N ratio.
