Abstract
A physical quantity detection system includes first and second physical quantity sensors, first and second power supply lines to which a power supply voltage is applied, a first decoupling circuit with first band elimination frequency characteristics, and a second decoupling circuit with second band elimination frequency characteristics. A relationship of a cutoff frequency on a low frequency side of the first band elimination frequency characteristics<a first drive frequency of a first drive circuit<a cutoff frequency on a high frequency side of the first band elimination frequency characteristics is satisfied, and a relationship of a cutoff frequency on a low frequency side of the second band elimination frequency characteristics<a second drive frequency of a second drive circuit<a cutoff frequency on a high frequency side of second band elimination frequency characteristics is satisfied.
